Nvidia GPU but laptop also has INTEL GPU drivers

New Dell laptop with Windows 10Pro. Laptop has an optional NVidia MX250 GPU. I installed that latest NV drivers. I also went into the Dell control manager system where it looked for updates for drivers. It updated A few drivers incl and update to BIOS but It also seemed to install Intel graphics drivers. Should I delete these or can I ignore this? I obviously only want the Nvidia graphics active and don’t want multiple drivers conflicting or slowing boot up times.

You don't specify the laptop.

Does it use nVidia Optimus graphics? Optimus | Technology | GeForce

If so, I don't know how to force it to only use the discrete nVidia GPU.

The laptop is a Dell Vostro 5590 with Core i7 10th generation 10510U CPU and 8GB RAM. It has the NVidia MX250 GPU with 2GB DDR5 memory. Display is full HD. Prior to logging onto the Dell update site, I do not recall seeing the intel drivers installed, only the NV ones. I might be wrong though. I am pretty sure it does not use Optimus graphics.
Win 10 Pro is installed on a NVMe drive.

It is configured as it is.What NVIDIA Optimus does is switch to Intel HD on non-GPU demanding applications to save energy and heat. It will only use the dedicated GPU when needed (like, running games for example).

All laptops with NVIDIA and Intel configuration have NVIDIA Optimus technology.

If the laptop is using battery power or multiple monitors it's beneficial having both GPU.
If it's used as a desktop replacement you can disable either Intel iGPU or Nvidia dGPU.
Options may be in the BIOS, Nvidia control panel, or by using device manager.

It is probably an Optimus Laptop. There are two drivers one for the integrated iGPU and one for the Nvidia MX250 that is correct. The video output is common to both. Just ignore it there is no effect on performance, they don't slow up boot time or conflict.

Dell tends to go it's own way. You may have some sort of configuration in the UEFI(BIOS) but normally the graphics are configured in the Nvidia Control Panel.
Most applications i.e. the Global Setting is on Auto-select, and on specific applications the default is set to Nvidia(default).

On mine, this is done with the Nvidia Control Panel, nothing in the UEFI(BIOS) and it does not like using the Device Manager to disable one of the Graphics systems.
Recently Windows 10 settings have included Optimus option settings, basically just repeating what is in the Nvidia Control Panel, seems to be in beta.
Settings > System > Display > Graphics settings > Graphics performance preference.

Thanks everyone, this settles it then, at least I know it is set up as it is supposed to be.

You will have an integrated GPU and NVIDIA GPU installed as well. For more intensive tasks the NVIDIA GPU will kick into gear and then it will hand back the reigns to your integrated chipset for tasks that don't need the GPU processing power. My Lenovo laptop used to do the same although I could change what GPU did what. Just make sure you run more intensive and heavy tasks with your NVIDIA GPU. For me there was a right click option which allowed me to 'Run with NVIDIA xxxx'. When I didn't use this option sometimes whatever I was doing would be ran using integrated graphics and naturally I would get poorer performance and sometimes crashing. No doubt the GPU switching will not be 100% accurate and depicting what task will use what resources and so you may have to intervene.

As for having both drivers installed, it's perfectly normal and nothing to worry about. If anything it's a good thing. Much of your everyday tasks will utilise to a greater degree your integrated GPU. Your NVIDIA GPU will kick in when extra processing power is required. But as a fail safe, there's nothing wrong with having your integrated graphics there to fall back on for everything else.

"For me there was a right click option which allowed me to 'Run with NVIDIA xxxx'. When I didn't use this option sometimes whatever I was doing would be ran using integrated graphics and naturally I would get poorer performance and sometimes crashing. "

Not on mine, definitely not the case, and nor should it be. After that "Run with" choice one or the other is the (default). This is set by the Nvidia Control Panel.

I run a 3D Graphics test on both the iGPU and Nvidia GPU. Neither crashes.
The Nvidia is fastest at the 3D graphics tests and applications using 3D graphics, but has no effect at all on most applications where few 3D graphics effects are used.

I have noticed a drop down option in the NVidia Control Panel that allows me to set preference to either use the MX250 GPU, Intel GPU or Auto. On Auto, I presume it will use the Intel GPU by default and auto switch the the MX250 only when graphics become demanding. I have left it in the Auto (default) setting for now. I presume this also gives better battery life and less heat.
