Touchscreen security

Hi,

Is there a way to password protect (or prevent access) to the touchscreen of the AirCard 790S device ?

I have changed the administration login password on the web page configuration for the device (from the default "admin") to prevent access to the setting on the web page, but even if I hide the SSID and Password from the front screen of the device, anyone can just access that information by going into the settings function via the touchscreen of the device.

Cheers.
