Blacklisting a GPU

Hello, I took a look at this guide https://www.youtube.com/watch?v=ID3dlVHDl0c.
To cut a long story short it tells you to make sure to have virtualization extensions enabled ( I enabled vt-d and vt-x ), and after updating your system run a script ( https://github.com/pavolelsig/passth...lper_ubuntu_20), reboot and your second gpu should be bound to vfio-pci.
After doing that if I run lspci -k I get this one



01:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050] (rev a1)
Subsystem: NVIDIA Corporation GP107 [GeForce GTX 1050]
Kernel driver in use: nouveau
Kernel modules: nvidiafb, nouveau
01:00.1 Audio device: NVIDIA Corporation GP107GL High Definition Audio Controller (rev a1)
Subsystem: NVIDIA Corporation GP107GL High Definition Audio Controller
Kernel driver in use: vfio-pci
Kernel modules: snd_hda_intel

Only the audio part is bound to vfio-pci.
Any suggestions?
Many thanks in advance, perhaps a noob like me shouldn't start learning ubuntu with these intimidating programs :)
