Are the drives a different size or is the SATA drive unpartitioned? If so then it should be easy to identify during installation which means you won't need to hide the device. I guess it'll mean that the new GRUB install doesn't pick up the original drive and setup a dual boot.... Is this the aim?

M.2 drive = 250GB with 1 partition(Ubuntu 18.04.5). Sata drive 1= 1TB with 8 (linux) partitions. Sata drive 2= 500GB with 3 Windows partition. Sata drive 3= 1TB encrypted. And 16GB(2x8GB) DDR4 mem.

If you read the above link, I tried installing Ubuntu-unity 21.04 and it messed up the M.2 drive that had/has(reistalled) 18.04.5.

I've worked with Ubuntu since around 1997, I think. At one time I had five OS's on 3 - 4 drives. Windows, Ubuntu *2 versions, Ultimate Edition(ubuntu), Ubuntu Studio.

I use grub customizer as the quickest way to update grub to my preferences.

I wanted to try out ubuntu-unity 21.04 and still have 18.04.
