Fedora 35 VFIO Issues

I’m trying to get VFIO working, using Wendell’s Ultimate Fedora 33 VFIO guide as kind of a pointer. I pretty did everything in the guide, including playing with the dracut loading order. I’ve checked if the shell scripts were executable, and that the kernel had IOMMU enabled. No dice. dracut seems to pick up the VFIO modules. Is there anything I could have missed? Thanks!

Should note I’m running NVIDIA Kepler Quadro cards. I should also note that I did this a while ago with Pop!_OS, so I don’t think this is a hardware issue.
