It seems the desired RAM is available on the manufacturer's QVL but not on the motherboard vendor's list. This suggests it should still function properly with your Z690 Aorus Master.
It seems the setup should be fine; I’d rely on GSK’s level. Likely Gigabyte hasn’t evaluated that particular model yet.
