I think you have to avoid
So to do the NPC interactions you need to
even going to the ledge that's before Rosaria entirely, since that circumvents Patches' trap entirely.
So to do the NPC interactions you need to
progress the level normally, but ignore the elevator that leads up to the higher rafters that lead to Rosaria, and then once you get to the boss room go to the elevator near it to open the door shortcut, and then there is a set of stairs that will lead you to Patches.
