MoCA Home network setup

I would like to utilize my coax outlets throughout the house for home network.  I guess I will need to install a MoCA splitter and a filter in my incoming coax cable box.  I would like to know if xfinity tech can help me install those?

I am using XB7 modem with bridge mode that connects to an Orbi router for home wireless network.

Below is a photo of my incoming coax box.
