How to disable TextField Touch Screen Cut Copy Paste GTK

When running a project on a Touch Screen and putting focus into a TextField a contextual Cut/Copy/Paste appears - and it’s very disruptive. It doesn’t appear when running over VNC, only when running to the Touch Screen display. It seems to being introduced by the GUI elements as they’re presented thru the RPi’s Raspian OS and whatever driver(s) are handling interactions with the Touch Screen. If anyone knows a good terminal command to enable/disable this behavior I’d be most appreciative. Thanks~
