A very quick way to disable is using boot arg.

Sadly, that doesn't increase the battery life

Yes, very correct. Provide your original ACPI files to check further.

Sorry for the late reply. Had to put this on hold for a bit.

The files I provided aren't good enough? I got the files trough MaciASL. Unfortunately, I am not able to dump the files with Opencore. I get error after error.

No worries. Use Clover to dump the ACPI files.

Probably, you did NOT followed the guide. First you need to disassemble and then find it in Terminal.

For your ACPI set, you'll find the exact information if you follow the guide.

$ grep -l Method.*_OFF *.dsl

DSDT.dsl

SSDT-11-OptTabl.dsl

SSDT-4-CflH_Rvp.dsl

SSDT-5-Ther_Rvp.dsl


$ grep -l Method.*_INI *.dsl

DSDT.dsl

SSDT-11-OptTabl.dsl

SSDT-3-PegSsdt.dsl

You need to use DSDT.dsl and SSDT-11-OptTabl.dsl to disable the dGPU.

This is not origin. But disassembled. Attach fresh ACPI. Make sure you delete the old ones before grabbing new ACPI set.
