how to turn off lockscreen camera quick access

Are you getting the camera open when you put the phone in a pocket? You could try disabling the Tap or Swipe to Wake setting. Swipe left to open camera still works but you have to wake the phone using the button first.

To my knowledge, you can't.

Regards.

Sorry I just reread your post and my suggestion doesn’t help because you were asking about swipe. I described how to delete the camera button from the Lock Screen.
