The specs of your machine is

It has MX250 with 4GB dedicated.

 No, you can't change dedicated memory for the MX250 card, it has a fix number, in this case 4GB.  For iGPU which shares system RAM you can't change its VRAM.

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
