mount different drives during win10/win11 dualboot

Hi,

I have win10 installed on a "non removable" NVME on a desktop machine. (obviously it can be taken out, but t's a pain to remove every time I boot into Win11)

I am also running Win11 from another HDD on that same box.

For security reasons, I don't want my Win11 to see my NVME as well as two other SSDs that I am using with my Win10.

Meaning my Win11 system should only see the partitioned hard drive it is installed on (I partitioned that HDD into a system and a data drive)
I also don't want my Win10 to see my the HDD that has Win11 and the data drive I created to be used with that system.

Basically I want to keep system drive and data drives between the two OS completely separate.

I know I can unmount, but from what I understand that's doe in the mount point of the drive and therefore wouldn't be different depending on what system I boot into.

How do I solve this issue?

Thanks
