Installing New Cable Modem without a Smartphone

Hello Xfinity Forum -

Is there any way to set up a new replacement (i.e. upgrade) cable modem on an existing home system without a smartphone? 

I received an email from Xfinity informing me that I should upgrade my cable modem from my current DOCSIS 3.0 unit to a DOCSIS 3.1 modem.  I would like to be able to install the new modem without having to buy a smartphone to do it.
