Could you describe how you prefer to de-activate a door? I can imagine two basic approaches:
One, lock the door “locked” but open. Thus, it simply cannot be closed unless somebody determines the combination first. On the downside, if somebody tries too hard to close it, leverage could cause some damage.
Two, withdraw the bolts and disable/remove the linkage so that the bolts cannot be thrown with the normal handle. If the door has pressure bars, those too would need to be disabled.
I’d guess there are details and variations in both cases.
I like what the Canyon Chophouse in Fort Collins (Colorado) did: during the initial rebuild from bank to restaurant, they put in a new roof support that is in the way of the door. Plus they cut a large hole in the side of the vault so it is no longer a closed room.
