turn off show my caller id

I have an iPhone 14 Pro Max, iOS 16.1. My mobile carrier is Xfinity. I wanted to turn off my caller ID for a call. In the past, I could do this by going to phone and there was an option to "turn off caller ID." When I search for Caller ID, it tells me to do that - but that doesn't show up on my phone. Where did it go and how do I turn off Caller ID?
