For Gen11+ platforms BSpec suggests disabling specific QGV points separately, depending on bandwidth limitations and current display configuration. Thus it required adding a new PCode request for disabling QGV points and some refactoring of already existing SAGV code. Also had to refactor intel_can_enable_sagv function, as current seems to be outdated and using skl specific workarounds, also not following BSpec for Gen11+.
