Proxmox graphical output to BMC instead of GPU

[showiproute]

Hello everyone,
I have a Supermicro server mainboard which comes with a dedicated IPMI chip for remote controlling the server.
Unfortunately as soon as Proxmox boots I can only see

Loading Linux 5.11.22-5-pve ...
Loading inital ramdisk ...

PVE boots without any issues so I guess it tries to output any graphic to my GPUs which are used for my VMs.
Is there a way to tell PVE to use my IPMI/VGA or whatever it is called instead of the GPUs?

normally this is a setting of the bios, usually something like "primary vga"...

Hello @dcsapak, yes within BIOS it is set that way - that's why it's a bit curious to me.

if you don't need the other gpus for the host (e.g. if you want to do passthrough) you could try to blacklist the specific drivers..
also csm enabled/disabled an uefi might change the default boot gpu

I have also blacklisted the specific drivers within modprobe.d directory.

root@proxmox1:/etc/modprobe.d# nano blacklist.conf
  GNU nano 5.4                                                                                                                               blacklist.conf
blacklist radeon
blacklist nouveau
blacklist nvidia

CSM could be another hot track I will check next time when there is a reboot needed
