My setup.
Unraid 6.11.5
AMD 3700x / GTX1650
ASUS TUF B550M PLUS / BIOS:3404 / AGESA ComboV2PI 1.2.0.B
Requirements.
1. Dumped vbios rom with GPUZ and removed nvflash header with hexeditor.
I had to dump mine even though techpowerup had exact model but i have 2 years newer revision.

2. Having your GPU in own IOMMU group
