No, it does not if the Wifi Chipset is disabled, because it uses wifi for location services (GPS would use way too much battery). That's exactly the problem: The wifi chipset is used for much more than just connecting to the internet.

You can also use the GSM Cell ID for this purpose. Once the user marks his/her home, grab the IDs of the surrounding cell towers and use these as trigger.

It's exactly what my phone does (Nexus 5X with Android 8), likely by listening to wifi passively ("which SSIDs are around?")

That doesn't sound like a disabled chipset...
