How do I turn off magnifier under accessibility short cut? Mine is checked and greyed out.

Hello. I would like to turn off the magnifier on my iPhone XS. I’m talking about the triple touch magnifier, the camera opens up with the zoom maxed out. I go to settings> general> accessibility> accessibility short cut> and try to turn it off but it’s greyed out. I can add other functions to the triple tap but cannot turn off the camera zoom. How do I manage to turn this off?
