Hi, trying to get Radeon RX 460 4GB GPU passthrough with a Asrock C2750 Avoton MB with Unraid 6.2.4 under Windows 10 with OMVF. Under graphics card only get VNC option.

I only have a onboard GPU and the PCIe GPU above. It's headless so I don't need console access. I don't think this mobo supports iommu so is there no way to have GPU passthrough to Win10 VM? Will upgrading to 6.3 allow it to work? Thanks.
