How to disable Onscreen Joysticks with blueprint?

does anybody know how I can disable the Onscreen Joysticks with a Blueprint or anyhow else?
I just need to deactivate it in the first Level an reactivate it in the following levels.


You need use Activate Touch Interface node.

In my example virtual joystick is Active. When I press “B”, touch interface disappear. When I press “B” again, touch interface appear.

That will help!
Thanks a lot!
