I'm not sure. There's nothing that says it has to be set up at church. However, the "setup" is very minimal as there's not really anything to configure.
Units are probably already enrolled. Look carefully on the label on the package to see what laptop goes to which unit. Anything you attempt to change will only affect your login. There is no shared login and the Guest account resets after logoff. The only thing left is to run updates. There might be something deeper that would affect all users, but I've not found any tools for that. But honestly, I'm not sure what I'd change.
