View the graphics card ID and write it into the configuration
root@pve3:~# lspci -nn | grep NV

root@pve3:~# cat /etc/modprobe.d/vfio.conf
options vfio-pci ids=10de:1ff0,10de:10fa

problem：
The corresponding device is not displayed here. Is GPV pass through successful?

Have you restarted after this?

You need to close the dialog after selecting the correct device. After that is should be visible in the hardware tab. You should be able to start the VM, if not, please report back the problems you had (logfiles, dmesg, etc.)
