Thank you, that indeed was the place. Wow, that is really buried deep in the settings!

You are in the wrong section. I would expect the option to disable the IGPU at:

advanced\amd cbs\nbio common options\gfx configuration -> set to disabled.

If all else fails you may want to try downloading bios v1.20 BETA and see if it gives you additional options.

I have a x670e PG Lightning with a Ryzen 7700x.

I'm looking for BIOS settings to turn off the built-in GPU, but the options on my 1.18 BIOS do not match the BIOS manual.

This should be under Advanced\Onboard Devices Configuration, reportedly under "Integrated Graphics Controller."

I do not have that setting at all.

The only menu item within that section regarding GPU is:
"Display Priority"

Has this option been removed?
