It will help stop the phone from broadcasting your location, but the danger is the private stuff on your phone getting copied if your phone is seized. Better to use a burner phone with nothing private (such as contacts) on it. Used that way you don't need multiple burners. Just keep it powered off til you reach the protest. I'd be hesitant to keep it powered (such as for mapping) on the way there, unless you don't mind GPS track potentially being retained on the phone. OTOH they will probably track you anyway, through license plate and face recognition.
BTW the cheapest place I know of to get phones with minutes is below, especially the basic flip phones that are probably better for this anyway.

Don’t they still broadcast low-energy Bluetooth?
I thought airplane mode or power-off disables that, but maybe on some newer phones, that is left running because of "find me". Hmm. BLE shouldn't be able to reach any cell towers though.
I think BLE is picked up by other nearby devices. That’s how you can find AirTags even though they have no cellular antennas.
This still happens with iPhones even when they’re powered down I believe.
The air tags have batteries..
Don’t phones have those too? 😃
