Issues disabling xfinitywifi

I would like to disable the public xfinitywifi hotspot that is being broadcast from my gateway modem. I am unable to toggle it off within the xfinity app or the xfinity website. The customer service line wasn't particularly helpful, and I have tried most of the things listed on this forum to no success. I'll probably end up cancelling the service, I'm not interested in having an unsecured wifi network in my home despite Comcast's claims of security.
