    This is factually incorrect. The option to disable Secure Boot becomes available when a supervisor password is set.

    I mentioned Ubuntu as my motivation for asking about Secure Boot so that the term would appear on this page and help guide others who are searching the web for solutions to the same problem. I'm sorry it mislead you.

    Set a Supervisor Password from BIOS, then you will be able to disable Secure Boot.
