How to start PC without graphics card in pcie slot?

[Jensjensesn]

I have a Acer Predator PO3-620 , Version 1.0
American Megatrends Inc., Version R01-A1
BIOS dated: Mon 13 Jul 2020 12:00:00 AM CEST

Intel® Core™ i7-10700F CPU @ 2.90GHz
 

The mainboard has 1 pcie 4.0 x16 and 1 full m.2 and 1 small m.2 (where a useless wifi adapter is currently sitting).

I have a cheap graphics card that needs to be plugged into the mainboard pcie slot, otherwise the pc won't start (since the cpu has no onboard graphics).

The problem is: I want to install a pcie x4 10GBE Network card into the pcie slot and don't need the graphics card. 

Is it possible to deactivate the check for GPU in the Bios? I didn't see any option for that.

Another idea would be a x16 to 2 x8 splitter and use the gpu with half the lanes and the network card at the same time, but I didn't find an adapter for that. (Only ones which split to multiple m2 or sata or usb ports)

 

Is there anything I oversee or what I can do to start the server and have 10GBE ?

This need BIOS pcie bifurcation support.

 

Or you may try M2 to PCIe slot Or USB display device.
