[Doubt] Remove hood at a specific moment of the game (explain inside)

[davoker]

I have a question about whether this can be done, I am going to set an example for the NPC Karliah.

Karliah, once the nightingale plot is over, she is always in the nightingales' room, but "she always wears a hood", removing the hood is easy, a simple edition in CK, but how can I make Karliah not have a hood just at a specific time?

For example, when Karliah and Brynjolf accompany you on the mission to go and kill Mercer Frey, she is wearing a hood, the problem is that the hood no longer takes it off, she always takes it from there.

Can it be done that Karliah once the story is finished with the thieves 'guild, do not wear a hood when she is in the nightingales' room? only there specifically, to wear the hood in the mission, but then remove it when everything is over.

Can this be done? I hope I have explained myself well, I do not have good English xD
