I had a similar problem a couple of days ago. Maybe try updating the initramfs by running this as sudo
update-initramfs -u
That was needed for me to get nouveau to stop taking control of the GPU
You’ll need to load vfio-pci before nvidia and blacklist nouveau.
This might help. Put this in your modprobe.d…
softdep nvidia pre: vfio vfio_pci
