Mine had the ability to turn of WiFi in settings. I provided it no real information, didn’t create and account, and didn’t use their app or interface.

It was a Samsung. YMMV with other brands.

You can disconnect them from the WiFi and block their ability to connect and then use a third party device for any apps you want.
