Gigabyte B450 AORUS M mod (without video card)

Hi Guys,

I need a solution to let my system run without any video card.
I’m using an b450 aorus m + ryzen 5 2600.
With video card the power consumption is much too high even if there isn’t any display attached.
The system boots without the card but loads the uefi default settings. So I need either a way to prevent this or to overwrite the default settings.
Any help would be great.

Thx
