At protests you should not bring your smartphone but instead rely on anonymous drvices such as Meshtastic.
If you want to bring your smartphone to a protest, set Airplane mode and communicate with others through Bluetooth or WiFi networks using Briar or Bitchat
Bluetooth and WiFi can be tracked as well, even with "anonymized" WiFi MAC addresses.
May I ask you how? Or if you have more info? No criticism here, honest question. Afaik the only way to do that would be to fingerprint a behavioural pattern, which albeit possible is surely more secure than cell communication.
The "find my" networks still function with randomized macs and "fully" powered down devices
