Asus stuck in Apto Setup Utility model number 540SA

Dec 3, 2018
I have tried the steps suggested in this site, to make a change to the Launch CSM under Boot, however, it does not allow me to change this setting. Only has the Fast Boot option enabled (allows me to disable) and has a Delete Boot Option but does not give me anything when I select that one. The Lauch CSM setting is currently set to disabled and does not allow me to change it.
