No you can't unlock it in BIOS. The reason: it allows you to overdone your machine then claim warranty. HP does not want you to do that.,

1 : ignore my bed English.

2 : I saw people on YouTube unlocking advanced bios with different keys according to their BIOS version, so how can you say that that I cannot.

3 : what is the problem with HP,  every other company give this option except this .

    Now I will shure think before buying or recommending HP products

Talking about VRAM, did you know

Integrated video (iGPU) does not have room for keep VRAM, it relies on System. System will work this out and allocate/assign spare/available system RAM to VRAM automatically when required up to max limit. System will also take VRAM back when required (the number is dynamic, not fix). During the good old days, we could do this from BIOS but now OS is smarter.

The following document shows Max shared RAM for Intel iGPU versions

Note: Recently people post Youtube on internet saying they can change using Regedit. Many people try but the results are unpredictable. You can try at your own risk.
