M4800 HIGH SIERRA working at 80%

[narayan]

NvidiaGraphicsFixup.kext deprecated. Replaced by WhateverGreen.kext. Make sure you read WhateverGreen documentation for the kernel flags associated with NvidiaGraphicsFixup functionality as merged into WhateverGreen.

I proved whatevergreen.kext with the bootflag nv_disable=1 but worked really bad. Even I lose HDMI display. I've back to nvidiagraphicsfixedup and works really good.

The boot was slowed by intelbacklight and I remove a pnfl code inside DSDT and VOILA, booting in 15 seconds.

I would like to improve whatevergreen @RehabMan

Make sure you read the WhateverGreen documentation regarding related boot flags.
I have no experience with it lately... (I have some Nvidia hardware on desktop, but I'm waiting for Mojave Nvidia drivers for Mojave).

PEGP should be renamed GFX0 (see desktop DGPU PM guides).

I've renamed PEGP to GFX0 but doesn't change anything.
What is this for? Brigthness?
Where are DGPU guides for high sierra?

It is for DGPU PM. You should read the desktop guides...
