Cant increase vram of an amd proccessor

[isael056]

i want to increase my ryzen 3 5300u vega 6 graphics card dedicated vram, but since the bios advanced options are locked, i cant find any way to do it, i tried to downgrade the bios to an older version but it sems like i cant, is there any other way to increase the vram?

Integrated video (iGPU) does not have room for keeping 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: Last year people posted Youtube on internet saying they can change using Regedit. Many people try but the results are unpredictable.
