I'm not sure what you are trying to accomplish.  If you disable
various BIOS interfaces, it is definitely going to break external code
that relies on those interfaces.  Basically everything under the "BIOS
interfaces" menu is low-level and should not be changed without
understanding the implications.  (If one disables the "boot"
interface, it should not be surprising that the machine can not
"boot".)

The use-case for disabling the boot interface would be for possible
embedded systems where one only needs SeaBIOS to execute option ROMs.
I don't know of any users of this, but it has been discussed in the
past.

Maybe if you explain what it is you're trying to accomplish then some
direction could be given.
