How turn off RTT??

[robtmrks]

Another thing I don't want that Samsung apparently thinks I must have. Is there anyway to turn off RTT? 

They seem to hate giving us a choice

Turn your wifi calling off. The rtt is only going to show up if you have wifi calling enabled

I have never had Wi-Fi calling turned on.

Sorry my mistake
