Wanted to share this for anyone else purchasing this laptop. HP is making it look like you can’t expand the RAM allocation to the GPU. I read a few sources that say that it’s locked in the firmware.
I was able to unlock it in Windows by installing the NVidia App - Download NVIDIA App
In the System / Advanced tab you can set the GPU allocation to 96GB RAM.
I wish we could push it to 112GB, these days every bit counts. Maybe there will be a future Linux hack that allows it.
happy hacking.
