This is a server side script, you cannot modify it or disable it
Only way to hide it is if the server has a chat command or button press to do so but other than my (now closed) servers I've never seen a server have that feature
So either ask them to implement it as a chat command/button press or play on servers that aren't running them (or if you're lucky they'll make an exception just for you in their script but I doubt it's gonna happen)
