Question Disable specific SSDs/SATA lanes

[Villateschle]

Hello, sorry if this gets convoluted. I have an Asrock fatal1ty z170 gaming-itx/ac motherboard (ancient i know), and I want to run two OSs on it. The first OS I want to run from my m.2 and two other SSDs. The second OS I want to run on two RAID 0 Drives. I would like to be able to switch between the two "OS groups" in the UEFI/BIOS and disable the sata lanes I'm not using. I don't want either OS intermingling. While in the bios, it appears that I can disable or enable sata controllers, but it is all of them. Is there a way to target specific ports? Thanks for your help and knowledge.

You want to use 1 OS on 3 drives and the other one on 2 drives for a total of 5 drives using 2 different OS?

Why?

So OS one is only on the m.2 and the storage for it is on two other drives, they are small because they are what I could afford at the time. and then the Other OS is going to be on the raided drives. I would like to do this because I will be using some software that I don't want to interact between the two groups. both will be windows, just used for different purposes. My case is a NODE 202, so pulling and replacing drives each time I want to switch would be tedious.
