Am I config PVE graphics passthrough correctly?

[cani1see]

I configed graphics passthrough according to some the online tutorial.
A windows virtual machine can use the GPU now, but this virtual machine is turned on on demand. Every time pve is turned on, and the windows is not turned on, it will still display these on screen

Booting `Proxmox VE GNU/Linux`
Loading Linux 6.xx.....
Loading initial ramdisk .....
_

My monitor will keep displaying these if there is no other signal source.
If the windows is turned on then turned off, it will not be displayed.
Am I config it correctly? Or is there some command that makes pve cancel this display signal?

I think you need to add pci-stub driver at boot so linux would not initialize it further for proxmox

*Untested* steps:

1. identify your GPU with lspci: lspci -nn write down [xxxx:xxxx] part
2. open /etc/default/grub with your favorite text editor and find GRUB_CMDLINE_LINUX_DEFAULT
3. add pci-stub.ids=xxxx:xxxx to it, replacing xxxx:xxxx with actual device identifier, your line should look something like GRUB_CMDLINE_LINUX_DEFAULT="quiet pci-stub.ids=xxxx:xxxx" (also you can add multiple entries separated by comma, if needed)
4. run proxmox-boot-tool refresh

and that's should be it; keep in mind that I did not check these steps, and that you won't be able to use this GPU to access PVE terminal w/o rescue mode!

Welp, maybe you can find success with this answer from askubuntu

1. check which driver is in use with lspci -knn
2. create and open file for blacklist rule e.g. nano /etc/modprobe.d/disable-gpu.conf
3. enter blacklist <your driver>
After a reboot driver should not be loaded anymore
