[Request] Asus Prime Z390-A iGPU Aperture Settings + Possible ARI Forwarding Enable?

I’d like to enable the aperture size adjustment and possibly enable ARI forwarding for SR-IOV. I’ve tried to mess around with the BIOS in AMIBCP, but run into an issue with it saying that the maximum number of bios strings has been reached.

I’ve attached the latest BIOS from the ASUS website. All help is extremely appreciated! TIA!
