hide control center

I have iOS 16.4.1 installed on my phone. If you don't see that option, it has been restricted. Check Setting>Screen Time>Passcode Changes. Or, if you have a configuration profile on your phone from an employer, that's another possibility.

You're not in the right place. Go to the Settings app. Go down to "Face ID & Passcode". Enter your passcode when prompted. Then, you will see the screen I showed.

Do NOT go to Settings>Accessibility.

Yes, there is such a setting and yes, Control Center is there. I think, perhaps, you didn't swipe down far enough.

Settings>FaceID & Passcode>Allow Access when Locked>Control Center>Off

You're very welcome.
