delete Voice and Narration tracks

Is there a way to remove these two tracks? Thanks

Remove them, hide them or delete what is on them?

Remove them totally . . . thanks.

Hide them I mean.

You can control the size of the timeline window.  Grab the bar inside the long box with your mouse and move it up or down.   Then you can scroll the content by grabbing the slider inside the small circle.  The result is you can see just Video 1 and Audio 1.
