I have an HP ZBook Studio G5 X360 with a built in Nvidia Quadro P1000 which has 4GB of VRAM, of which only 2GB are ever used.  I turned off the Intel integrated graphics and am solely relying on the GPU for graphics processing.  The problem is the laptop has 32GB of memory but it can only make use of 16GB at any time because half of the memory is reserved for graphics processing (shared GPU memory), but that memory is never used because my GPU's VRAM usage never goes above 90%.  I read in some forums that some laptops come with an option in the BIOS to reduce the shared GPU memory, however my laptop's BIOS does not have that option.  Would it be possible to create a BIOS update for my device and all other HP device to allow the system to free up the 50% of unusable memory, which in my case adds up to 16GB of unused memory?
