Unsure if it's important but I connected my thunderbolt cable closer to the charging port.

I originally tried to get my egpu running with an amd card (5700xt) but couldn't figure it out, constant errors such as error 12 and 43. Installed the nvidia card and it worked relatively easier comparatively. I was faced with error 31 but once I tried apple_set_os.efi it worked with no issues. Now I'm able to boot without apple_set_os.efi but still do so as user @macnexus suggests the laptop runs quieter and cooler when the dGPU is deactivated through apple_set_os.efi
