Primary Display, VarStoreInfo (VarOffset/VarName): 0x4C3,
DVMT Pre-Allocated, VarStoreInfo (VarOffset/VarName): 0x49F
DVMT Total Gfx Mem, VarStoreInfo (VarOffset/VarName): 0x4A0

the variables are these

0x4C3
0x49F
0x4A0

You can change values by RU shell :

https://casualhacking.io/blog/2019/6/2/d...-s-hardware-cpu

https://ruexe.blogspot.com/

choice the GUID and get the varibles then change values

ie for this 0x4C3 you can have these values :

0x00
0x01
0x02
0x04

One Of Option: Auto, Value (8 bit): 0x3 {09 07 2E 06 00 00 03}

0x29B7E One Of Option: IGFX, Value (8 bit): 0x0 {09 07 AC 07 00 00 00}
0x29B85 One Of Option: PEG, Value (8 bit): 0x1 {09 07 AD 07 00 00 01}
0x29B8C One Of Option: PCIE, Value (8 bit): 0x2 {09 07 E1 09 00 00 02}
0x29B93 One Of Option: SG, Value (8 bit): 0x4 (default) {09 07 AE 07 30 00 04}

So you can write into the NVRAM variable any of these values and not others !!!

And so on ...

let me know
Regards

Sorry I had not noticed I was answered on another page :P

Do you have answers for these 4 other questions?

I have a few questions:

1. How can I tell what is the 'current' value.
2. Is there a way to unlock hidden menu from this?
3. Is there a way to change one of the 3 video ports: Mini DP, HDMI or Type-C (Thunderbolt) to use Internal Graphics (IGPU / Intel)
4. If I screw up, can I fix without opening/disassembling the laptop
