For this example we will be using Do Not Disturb, but you can select any Focus mode that you'd like to assign a customized Lock Screen.
Tap Do Not Disturb.
Scroll to and tap Choose.
Tap Create a New Lock Screen.
You can also select one of the Lock Screens you've already created.
Tap on your preferred selection.
Tap Add.
Tap Set as Wallpaper Pair.
If you want to have a separate Home Screen wallpaper from your Lock Screen, tap Customize Home Screen and select one of the options at the bottom of the screen.
You've completed the steps!
