How to get the current camera mode and set it to IVA

[Cryphonus]

Pretty much what the title says, i am trying to change the camera mode to IVA camera and making the user unable to switch to other camera modes for a duration.

I used the following line to get the current camera.

Camera myCamera = Camera.current;

But i need to use CameraManager class to change my current camera and i just couldn't make the connection between the camera and cameraManager class. In short words how do you change the current camera mode to IVA?

Update and bump:

I can set the current camera mode to IVA by overriding OnUpdate. However something instantly pulls it back to Flight camera. So its like switching 100 times in a second between these 2 modes. Any ideas?
