Disabling Multi Touch Gestures in Ubuntu 16.04.4 LTS Desktop

I am Using a Critical Application which needs to be on the screen all the time , and user should not be able to logoff or should not be able to acess any other Application , The Device is equipped with Touch Panel USB Type . However the ubuntu has Default Multitouch Gestures which allows the user to Change Placement of the Window of runnimg application with 3 Finger , Also the Pinch Fuction with 5 Fingers allow user to Have Access to BackGround applicatio , I would Appreciate if someone help to findout a way to Disable the Multi Touch Gestures ( Allowing Single TAP function Only with Touch).

This worked for me:

gsettings set com.canonical.Unity.Gestures windows-drag-pinch false
gsettings set com.canonical.Unity.Gestures dash-tap false
gsettings set com.canonical.Unity.Gestures launcher-drag false
