Private file : editing behavior of 'escape'

I am deploying a private file for an install which includes an “exit” button on the interface. I’d like to disable the functionality of hitting escape.

Currently it doesn’t exit the program, but it does unlatch the borderless perform window and the user can’t get back to the full screen, no borders perform mode. So hitting escape inevitably means they have to exit the program anyways. Is there a way to just stop escape from doing this?

I know previously there was an option for private files that would allow escape to quit or not, but I don’t see it anymore in 088 13100.

Thanks!
