Hello.

Sorry for bumping and old thread, but I think my respond mmight be useful.
There is an option to see post/bios phase on eGPU using Skull Canyon as a PC.
You need to swith few options in UEFI to achieve this :

- primary video output needs to be TB (secondary is not important, so might be HDMI/DP or disabled),
- you need to enable only UEFI boot, CSM/Legacy need to be DISABLED,
- in boot section you should trigger all TB option (there is a few).

After that eGPU will be detected as a primary adapter in BIOS/UEFI and Windows (probably anywhere else) so you don't need to disable iGPU or switch anything.
iGPU will be still enabled but not used until you wanted to.
There will be no problem with installing windows etc.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

I recently come up with the solution for this, at least for my setup nuc6i7kyk + tb3 core x.

On boot options enable boot through Thunderbolt and TB4 USB. The IGD primary display seems to be irrelevant for this. 

This way I could finally get the eGPU video output to work even when on the BIOS. Still struggling to turn of the IGD though.
