Can MBP 16" use only iGPU on bootcamp?

Is it even possible? I have done all this EFI tutorial https://egpu.io/forums/bootcamp/macbook-pro-16-windows-egpu-error-12-fix/

Now I have both iGPU and dGPU enabled, via task manager I can see that windows now uses both of them.

/ wanted to take a screen shot here but not possible on windows, there is no button.. /

If I disable 5300M via device manager, I dont get full performance from intel gpu and cannot change resolution, everything is lagging, works like on basic display drivers... So is there a way to fully switch to internal gpu only?

@vyt_autas, The Intel iGPU in 2018-2019 15-in and 16-in MacBook Pro cannot drive the internal display. While they may seem activated and functional, force-attaching the iGPU to the internal display would cause black screen issue (after a couple seconds of flashing white dots).

Perhaps you could leave some feedback for Apple.

I've done the same, and not sure if Apple listens or will do anything at all, but worth a shot?  And hopefully if many people complain and ask for enabling iGPU in bootcamp officially for Windows based automatic switching and better battery life by driving the internal display with the iGPU, perhaps they will listen?

@vyt_autas, you can hit Start (command on Mac) + Shift + S to paint a rectangle that will be taken as a screenshot in memory, then you can paste it into paint or anywhere really.

Or you can use the Snip tool in windows to have more options and editing tools.
