Hi
What I would like to do is install two instances of windows 10 on one machine, each on its own ssd hard drive with a normal hard drive for data etc.
However I do not want them to be able to access / see the other operating systems drive, thus creating two separate systems
Any suggestions
That suggests to me you have 2 SSDs and only 1 HDD in which case there probably is no way to prevent them intermingling.with a normal hard drive for data
Any drive can be hidden from File Explorer by the simple expedient of opening Disk Management and removing its drive letter. You could boot into each system of a dual-boot machine then remove the drive letter of the other system's system drive.
The problem comes if the data drive is shared between the two. If the 'Users' folder is kept here it's going to contain users from both systems - this may well be a problem as the 'Default User' is the template used for creating new user accounts.

Both installations will have one ssd and one normal dive (four drives in total)

The problem with that method is that I would not be 100% convinced that a virus / malware could not map those drives.
If you have only the hard drive/ssd you want windows on and install windows; do that twice, once for each of your 2 systems. Then boot into each system, go to disk management, right click the drives you do not want to see, select 'change drive letter or path', next and click remove, it will remove the drive letter from the drive. You will not be able to 'see' the drive in explorer, but the OS will know there is another drive present, but it won't show up in explorer. It will show in Disk Management and in Device Manager.
One drive will be set up in BIOS as the primary boot device. The other drive will be able to be booted into by using the one time boot menu key or changing the boot priorities in BIOS.
Ransomware works its way through local drive letters, that includes mapped network drives. A very few can find unmapped shares on other machines on the network. I know of none that can find and mount a partition which is not in use.
Malware that infects the MBR is going to corrupt all partitions however you protect them. The only sure protection is to swap out the system drives and only have one in the machine at any one time.
I have one. I use only 2.5" SSD/s mostly with 1 2.5" Hard drive. I have used one similar to this for a few years and it works great and would do exactly what you want.

I did simply my set-up a little in my original post, the main boot drives are m.2 (not traditional ssds), screwed into the mb, so swapping is not practical.
The aim is to have two separate instances of windows 10, that can not see each other, one for the kids to play games, one for the adults to work. obviously I do not want my work one to get a nasty surprise when the kids do something silly.
