How can I prevent a top swipe revealing the navigation bar?

Hi,

I'm developing a "kiosk mode" style app on the Zebra PS20. Using the profile manager I've managed to hide the bottom buttons and stop access to the top navigation/status bar functions. However, I can't find an easy way to stop the swipe from the screen top revealing the navigation bar.

A simple swipe down near the top reveals it for a few seconds:

For Target MX Version 8.1 I'm altering the UI Manager settings:

• Enable/Disable HomeKey: Disable
• Pull Down of Notification Panel: Disable
• Settings Icon on Notification Panel: Hide
• Network Monitor Notification: Turn Off
• Enable/Disable NAvigation Bar: Disable
• Magnification Gesture: Turn Off
• Enable/Disable SplitScreenMode: Disable
• Enable/Disable Do Not Disturb: Disable
• Enable/Disable Multi User: Disable

The rest are at their defaults.

I thought that "Pull Down of Notification Panel" would have solved it but apparently not.

Is it possible to prevent the swipe using the API or profile manager?
