can you disable the motion permission in the OS settings?
Under AOSP and most customs OSes, no. It’s not a standard, exposed permission. GrapheneOS does have a toggle for it, though, and I’ve found most apps don’t need sensors.
Sensors permission toggle: disallow access to all other sensors not covered by existing Android permissions (Camera, Microphone, Body Sensors, Activity Recognition) including an accelerometer, gyroscope, compass, barometer, thermometer and any other sensors present on a given device.
