You can't, if you have already used it.
If you set up Two Factor, but have never used it, you have two weeks to cancel. If this applies, see more info below.
Tap Settings
Tap your name at the top of the screen
Tap Password & Security and enter your Apple ID Password
Tap Two-Factor Authentication for the disable option
