Iamrmz There's a toggle in the Developer options but it is not intended for regular users. Please do not touch it as it's primarily for app and operating system development.
As stated in the below link, in standard Android environments, this permission to toggle sensors per-app does not exist. By default, apps are assumed to need sensor access. GrapheneOS introduced the 'Sensors permission' as a per-app toggle, a unique addition. This method is designed to prevent unintended disruptions in app functionality. It's important to note that disabling sensors globally might interfere with the operation of some system applications.

The GrapheneOS developers provided thorough and in depth information regarding Sensors in this discussion as well: https://discuss.grapheneos.org/d/6310-why-so-many-apps-need-sensor-access
