On Android, find Location Services in your system settings and look for Google Location Accuracy. The description for it on my Galaxy S21 reads:

> Google's location service improves location accuracy > by using Wi-Fi, mobile networks, and sensors to help > estimate your location. Google may collect location > data periodically and use this data in an anonymous > way to improve location accuracy and location-based > services. > > Turning this off will result in your device only using GPS > for location. This may impact the accuracy of location > used by apps such as Maps and Find My Device.

Based on that description, that should turn off the data collection, although it can also make GPS fixes take longer, and there may well be other apps collecting this data as well.
