(Please solve) After using i915-sriov-dkms, I have to connect the display device to reboot the system.
The README.MD doesn't seem to mention this reason.

PVE V8.2.7

Why do I have to connect a physical display device for virtualisation?

Here are the test results

1. Black screen without connecting a pre-connected display device, can't be solved when the system is already started.
   2)Connect the pre-connected display device, and start the system again, it works fine.

1. I encountered a similar situation on PVE, but I know where the problem is, the machine is not connected to the display device where it was originally stored, and I can't access the PVE site, but the PING passes.
2. When I moved to another place to connect the display device and restarted the machine, everything was fine, PING passed and at the same time I visited the PVE website, and the display device (PVE image appeared) did not have any error messages.
   3.Maybe i915-sriov-dkms preset this point in the preset modification.
3. Solution (1) must be connected to the display device / HDMI cheat
   
   (2) ask for guidance to modify the default connection to the display device problem.

Therefore, I would like to ask if there is a way to start the system without running the detection of the physical display device?
