Setting up Android without HUD

Hello,

I made a Project for Android.

Now there are these Buttons to anvigate and I dont know how to remove them or disable them. I want to Blueprint my own stuff because All I want is basically a static Camera which can not be moved and make a 2 D game where I can shoot things that appear on the screen. Therefor I just have this static camera looking at the scene and spawning objects that the user can shoot and get Points. How can I achieve this?

There mobile virtual controls settings in Project Settings->Input

Thank you very much
