Decrease VRAM amount on ASUS Zenbook UM431D

[ugurcan]

Hello, is it possible to decrease VRAM amount for Asus Zenbook UM431D ? Currently its getting 2 gigs of ram and I dont need that much ram going to VRAM. I got 8 gigs of ram and its bottlenecking my apps especially android studio... I tried to change in AMIBCP but there is no option for UMA buffer size. Is there any other way to change this like in GRUB or smth?

Here is the bios dump I got from amiflash(AFUWIN)
