thank you for the quick reply. Ok with the swap but as you can see the rx570 will not be in its own iommu group. i guess i'll have to follow some steps from : https://youtu.be/qQiMMeVNw-o

hi all, first i'm new to unraid. Here is the problem, i have two GPUs, on the 16x rx570, and on the 4x gtx660. i want unraid to boot with the gtx660 as gpu so that i passthrough the rx570 to a windows 10 VM. i tried by searching in the bios if i can do so, and didn't find anything. can someone help? some information below if needed.
