It's using .override_only = PCI_ID_F_VFIO_DRIVER_OVERRIDE, so it only matters if the user was already planning to override the regular driver with VFIO one (using driver_override sysfs). So if it worked on i810 or other odd parts using regular vfio-pci, it would work with xe-vfio-pci, as both are using the same underlying functions provided by vfio-pci-core. -Michał
