Also enables full passthrough. GPU tested Nvidia RTX 2080, Nvidia 1050ti

#Unbind from current driver (add ones that have not binded to the vfio driver)

echo "10de 0fb9" > /sys/bus/pci/drivers/vfio-pci/new_id
#unbind USB:
echo "0000:09:00.1" > /sys/bus/pci/devices/0000:09:00.1/driver/unbind

#Bind to vfio-pci

echo "0000:09:00.1" > /sys/bus/pci/drivers/vfio-pci/bind

#Rescan PCI
echo 1 > /sys/bus/pci/rescan
