Set the nvram variabe `gpu-power-prefs` to 1 on dual GPU MacBooks to enable the iGPU

efi-gpu-power-prefs

Set the boot gpu on dual gpu macbooks to the iGPU. I'm assuming you are using grub, and have installed gnu-efi.

1. Spoof apple-set-os, you do not need to do the nvram thing (this repo does it for you)
2. Clone the repo and run this:

   make
   make install
   sudo grub-mkconfig -o /boot/grub/grub.cfg
   

3. In the grub menu, select the "Enable iGPU" option, it will power down and then you can boot again with the igpu.
4. If you boot macOS, you will need to repeat step 3 as it gets reset.
