Bought a new RTX 3090 but cant see the GPU on the HiveOS

HI,

I couldn’t find the Bios setting. I have a dell optiplex 3010. I cant find where is the option I can change to gen 2 to solve this problem

Fwiw… I had issues getting my card recognised on my msi motherboard when I used uefi + csc. Had to use uefi alone and disable secure boot stuff…
