By default, when you present a screen inside a navigation layer, the presentation screen will display a Navigation Bar if the root layer has one. You can remove the navigation bar on the presentation layer by applying the Navigation Bar Hidden modifier.
To hide the Navigation Bar on a screen inside a navigation layer, apply the Navigation Bar Hidden modifier to the screen that you are presenting. In this example, it’s called Page 2.
To only hide the Back Button of the Navigation Bar on the screen that you are presenting, apply the Navigation Bar Back Button Hidden modifier instead.
