If you choose to enroll in Face ID, you can control how it's used or disable it at any time. For example, if you don't want to use Face ID to unlock your device, open Settings > Face ID & Passcode > Use Face ID, and disable iPhone Unlock or iPad Unlock. Within supported apps, you can enable Face ID for authentication.

Just so, do you have to use Face ID on iPhone 11?
Remember there is no Touch ID on iPhone 11, iPhone 11 Pro, iPhone 11 Pro max, iPhone X, iPhone XS, iPhone XS Max, or iPhone XR, as Face ID is the biometric security replacement.
Also, why is my face id not setting up? If you still need help, reset Face ID, then set it up again. Go to Settings > Face ID & Passcode and tap Reset Face ID. Then tap Set up Face ID to set it up again. If you can't enroll your face, take your device to an Apple Retail Store or Apple Authorized Service Provider or contact Apple Support.
