Thank you for the correction! I saw multiple news articles several years ago saying that Intel would be dropping support for BIOS mode by the end of 2020, but it appears they've been dragging their feet. In the meantime, they seem to have been making moves in other ways, such as not supporting BIOS mode when booting with integrated graphics on 11th gen processors ( https://www.asus.com/us/support/FAQ/1045467 ).
