Answer 1

You can't disable start and search button . But you can manage back button taps if your app is in foreground.

You can use BackPressed event to manage back button taps . Use the below code to subscribe to the event.

 HardwareButtons.BackPressed += HardwareButtons_BackPressed;

event handler

void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e)
{      
        e.Handled = true;  // this will cancel the navigation         
}
