ROG Crosshair VIII Extreme: how to turn M.2 drives off?

[Baio73]

Am I completely dumb of the BIOS lacks this option?
I mean, I want to simply switch off some M.2 slots or the DIMM.2 one to make SDDs not visible to the OS without having to phisically disconnect them... not that hard thing, I think...

Computer management, storage, disk manager snap in, unmount the device.

You could also disable the device driver, but the above is a nice way.

What is the actual purpose ?

Well, this is a software solution, but I need to do it on the hardware side.
The purpose is OS installing... Windows often creates new partitions on secondary disks even if you're installing it on the primary. And you end discovering it when you remove the secondary unit and the OS does not load anymore! :mad:
I always prefer to install Windows with the minimum possible hardware.
