I'm pretty sure VNC can be configured to work that way. But I don't know the details of configuring it.
I'm sure there is some text file where the results of that GUI are stored. Possible some VNC documentation may tell you where the text file is. Or maybe you need some more brute force method of determining which files are modified by running the GUI.
Once you know which text file stores the setting, you could bulk change that for all users. Or you could put something in a login script to change it for the current user. Or maybe there is a shared text file that can control it for all users.
