I've seen a few of the following features greyed-out, but only a couple of the features allow me to grey them out so that a user can't tamper with the changes:
Under, Users & Groups...Login Options... - display login windows as: name & password - show fast user switching
Under, Energy Saver... -Turn displays off after (both tabs "battery" & "power adapter")
Under, Sharing... -Remote Login
Under App Store... -automatically check for updates
If anyone has tips on greying-out these areas, that would be great to test
You can get access to configuration profiles in the main JSS web interface. Select Computers at the top of the screen and then Configuration Profiles in the sidebar on the left.
If you need to create custom profiles you could look at @justinrummel's blog here: https://www.justinrummel.com/using-mcxtoprofile-with-the-casper-suite-for-advanced-configuration-pro...
