> I see, that's indeed a very good reason to implement it differently. […]

As a final result I would like to use this functionality to be executed via libflashrom and fwupd. So I can add it as an unlock option, but then we have to add another table of functions, e.g. board_unlock_me.

Just need the decision what would be the best. I kinda opt for the board_unlock_me and a separate argument for internal programmer for example. Since board_enable may have different silicon than Intel, it may be wise to not bloat it even further.
