I am using proxmox, passing through a GPU to a windows VM. All works fine but recently, vfio started loading as driver for the wifi card and the ethernet port I have on the motherboard. Leading to proxmox not being able to access the network anymore. I solved it by plugging a USB ethernet adapter and using that as main network device for Proxmox. Now I am trying to figure out a way to restrict vfio to only load for the GPU. As far as I understand, all three devices are on different IOMMU groups so I don't understand why this is happening.
Here is my GRUB config
GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset intel_iommu=on iommu=pt"
