Install iOS 13.3.1 for a New Location Services Toggle
The iOS 13.3.1 update includes a new toggle that lets owners of newer iPhone models disable Ultra Wideband.
Apple added the toggle after users discovered the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max would continue to track a user's location even when the device's location services were toggled off. The company claims this was due to the Ultra Wideband chip on board these models.
The toggle is found inside the Settings app. You must then head to Privacy then Location Services then System Services.
From there, you can now toggle off the "Networking & Wireless" option.
