How do I enable/disable Night Shift mode in iOS 11 or later?

The Night Shift toggle has been removed from Control Center in iOS 11 (Public Beta 1). There is also no option to add a Night Shift toggle in the Control Center customization settings. To manually enable or disable Night Shift you now have to navigate to Settings > Display & Brightness > Night Shift. From here tap the "Manually Enable Until Tomorrow" to enable Night Shift on your device.
