Joint account: is it possible to opt out?

I created a joint account with my flatmates to sort out bills etc but I’m going to move out soon and I’d like to opt out from the joint account without necessarily closing it.
Is it possible?

You’ll need to close the joint account.

A joint account without you is just a normal account, which they have already.

You will have to close the joint account, though you should still be able to use your Monzo current account.
