How do I make the camera into first person in another place?

hello, this might be very confusing but anybody knows how do I make the CameraMode into LockFirstPerson in another place/stage? since in the first stage in my game the CameraMode is in Classic and I also want in my second stage in my game I want the CameraMode in LockFirstPerson just like in the game called “Cheese Escape”, where the person go in that green locked door and teleported to another place while in first person?
