Bios Mods -The Best BIOS Update and Modification Source

Hi, I'm looking for unlock Lenovo S340 BIOS, is the same BIOS in all the S340 versions. The thing is I want to increase the grafic vram over 2GB but Lenovo does not allows me to do that even when the APU (Ryzen 5 3500U) can do that.
Here the BIOS I use currently:
