Option in BIOS for memory allocation for graphics (ASROCK A320M-HDV/Ryzen 2200g)?

Hi there, long time lurker first time posting!

I just built a PC using a Ryzen 2000g and ASROCK A320M-HDV combo. Everything is fine, however I've noticed that there's only 1GB (out of 8GB) of memory reserved towards the graphics. The spec sheet says it supports 2GB and I've read that AM4 boards notoriously default APU memory to lower amounts and require a change in the BIOS, but for the life of me I can't seem to find the option for it. Or did I choose wrong and pick up a mobo where it can't be changed?

Any help would be appreciated :)
