Hi Makary,
Currently, Night Light is a user-level feature designed to promote eye comfort, and it's not exposed as a configurable setting in Group Policy or standard administrative templates. As such, there’s no officially supported method to disable or restrict access to Night Light via Group Policy.
That said, if you're managing devices in a controlled environment—such as in education, enterprise, or kiosk scenarios—you might consider broader device management strategies. For example:
Using Assigned Access or Kiosk Mode to limit access to system settings
AppLocker or Microsoft Intune to control which apps and settings users can interact with
Feedback Hub: You can submit a feature request to help our teams prioritize enterprise-level controls in future Windows releases
We always encourage safe and supported configuration practices to ensure system stability and user experience. And if this answer helps clarify things, feel free to hit “Accept Answer” so others can benefit too 😊
T&B, Harry.
