Indeed it doesn't show the same options. This is what I saw when I went to Startup Security Utility:
(*) Full Security:
Ensures that only your current OS, or signed operating system software currently trusted by Apple, can run. This mode requires a network connection at software installation time.
( ) Reduced Security:
Allows any version of signed operating system software ever trusted by Apple to run.
[ ] Allow user management of kernel extensions from identified developers
[ ] Allow remote management of kernel extensions and automatic software updates
There's no option to turn on or off a firmware password, instead I had to login with a local administrator account first before I could access anything under recovery options.
There doesn't appear to be a way to set "No Security" as an option either. At least from the GUI. Maybe it's possible from Terminal somewhere. But it seems unlikely or undocumented for now.
