5D iii lock switch question
Sorry Star button wont help you either since only the exposure measurement is held. Your only option is to leave the highlighted parameter in the quick menu a few boxes away from TV/AV, so a couple of inputs would be required to change a value accidentally. Ideally, the lock switch function menu would also include the Q button, then you would get want you want, but it does not.
