I want to increase DVMT Memory

[Legendarystatue]

So I want to increase my Dedicated Vram but i don't know how my Graphics is a AMD VEGA 3 Mobile GPU but somehow i can't find it in Bios also i can't find BIOS because of how old my Computer is i can't run most things not even Minecraft Windows 10 edition and it's starting to suck really bad. Here is some Pictures of my System's Video Dedicated Memory and i know i just upgraded to 16gb's of ram since it registered but somehow it only uses 1gb of Video memory not 2 or even 4

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 (I can't find a similar list from AMD).

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