Which model are you referring to? I have a Maximus X Hero Wifi. The latest BIOS is 2701, released 11-Aug, 2021. That is almost 18 months ago but Asus has updated this BIOS 16 times since the mobo was released. I am by no means an Asus fan boy but I think that is pretty good. It is normal for BIOS updates to slow down and stop after a while for boards that are several years old. I have not had any trouble with Blue Screens or XMP.
