If the BIOS is new enough to support the 2200G then it will be on by default if you don't have another graphics card. Unless the box for the a320 said it was gen2 compatible (or something similar) you probably don't have a compatible BIOS.
It's all booted up fine windows 10 is all working but just not showing vega 8 graphics, I've seen in the bios is video out says igfx video or gpcie it's currently set to that, also my bios is on version 4023
