BIOS VERSION

3.05

Describe the bug

When booting the desktop, if no displays are connected, the bios waits until one is connected with a 30s timeout

The type of display does not seems to matter. I tried with HMDI and USB-C display with the same behaviour. Once connected the boot continue immediately

Steps To Reproduce

Steps to reproduce the behavior and see it in action:

1. Start you computer with a screen connected

2. Once booted check firmware boot time with systemd-analyse time for me it's around 7s

3. Start you computer without a screen connected

4. Once booted check firmware boot time with systemd-analyse time for me it's around 38s

Expected behavior

BIOS should not wait for a display to be connected to boot. At least not with Quick Boot option enabled
