GPU gets recognized even with -wegnoegpu boot-arg

i got it to work but now i have a problem where when i boot my pc with MacOS (and my GPU is not connected with hdmi) my bios signals a Display Memory Read/Write Error. even when my boot arg is -wegnoegpu (and when i connect it with hdmi it freezes in the verbos because it detects my GPU) it only boots when i unplug my gpu's power suply
