Is there a reliable way to disable fast user switching (programmatically or via profiles) in macOS 10.13 and 10.14?

Thanks, -- M

Here is the command:
defaults write /Library/Preferences/.GlobalPreferences MultipleSessionEnabled -bool 'NO'

You can also create a profile to disable it, and with a profile they will not be able to bypass the setting. It is under LoginWindow -> Options 71a587619df94ea88f50f95bdc976ef2

I found this however doesn't stop concurrent user login (fast user switching) through remote access (screen sharing, ARD or VNC). It only removes the switch user on the lock screen.
