Once a token is issued it is valid until it experies. There is no way to disable a token short of changing the secret used to sign them which would invalidate all existing tokens for all users.
I actually suggested exactly that elsewhere. It would be a nuclear option, for sure. Since it would require every single user to log back in. But it would 100% without a doubt stop the attacker in their tracks.
That's bad design because you can bind a user token to a per-account value which can be rotated to deprecate tokens
