AsRock X399 Fatal1ty Professional Gaming "Enumerate all IOMMU in IVRs "

I can’t seem to find the “Enumerate all IOMMU in IVRs” setting in my BIOS. I have been having trouble passing a GPU to a KVM in UnRAID and this seems to be the solution. However, I can’t seem to find the setting I have virtualization, IOMMU and SR-IOV enabled, but I still get crashes with the error “libvirtd tainted”. This is followed by a stack trace which shows that an Nvidia PCI device is the issue. Anyone else with this board experience this?

Is IOMMU set to ‘auto’ or ‘enabled‘? The two settings have different behaviours for GPUs
