I did an upgrade install on one of my machines and had the SSD show up as removable afterward. It already had an AHCI driver installed from Windows 7 so after a little head scratching I figured out a way to uninstall the driver and reinstall it (a Windows 7 driver too). That worked.
Try uninstalling the Intel Rapid Storage technology, then recheck the BIOS to insure no hot-swap is selected........
I have read where this has solved the problem you are describing.......
Hope this helps...
I tried that link above and it didn't change anything. Thanks for the suggestion though.
I'm curious if there's some other registry edit I could do to treat it as internal, since people using various other SATA controllers like Marvel have had success with that.
You've got to find a SATA AHCI driver that works.
Looking at the drivers offered for your motherboard it is clear (to me) that Asus wants you to use the Intel Rapid Storage Technology Driver.
There has been some indication that I have noticed that Windows 10 can sometimes not play nice with the IRST driver on some systems. I can't tell if this is because people are installing the wrong version of IRST for their particular motherboard, or installing an older IRST driver for a previous operating system that is for their motherboard and not using compatibility mode.
There seems to be a consensus among Windows 10 users that this problem is simply an annoyance, and since it does not affect performance it can be simply ignored. If that is also the attitude of the Microsoft folks then there will not be a big push to correct it anytime soon. If installing IRST does not correct your problem then you may be stuck with doing as you are told: just live with it.
In the device properties list, the hard drives list both a hard drive and portable device, of which I can disable and uninstall the drivers. Since as far as I know the portable devices don't do anything, I figure I can attempt to disable and uninstall the drivers.
My only question is if I back up my computer will I be able to reverse something like that?
If by 'back up my computer' you mean make an image of your disk (or just the C: partition), then yes, completely recoverable.
However, any internal hard drive is a basic component and Windows will install at least a generic driver as soon as you start up, so unless there is something specific about the current driver that allows you to do something outside of ordinary then you will see no changes in function.
It is not a risky process.
One problem you may have is that Windows stores all the drivers you have installed in the Driver Store. If an old driver remains there then Windows may decide to reinstall it. If you are asked to delete all drivers along with uninstalling the device, do so.

Do you have Intel Rapid Storage Technology Driver installed now? (One of the versions posted on your motherboard's website)
Have you ever installed IRST?
