Have you tried driverctl as a means to bind them to vfio-pci? The pci-stub driver is usually built statically into the kernel allowing it to claim devices before modules, ie. pci-stub.ids=10de:1ad6,10de:1ad7. The only way you could have previously left them bound to default host drivers would have been forcing group separation with the ACS override patch (not recommended).
