MoCa and Router

Hello.

A few days ago, a Comcast representative came to my house and informed me that he needed to put a MoCa spliter on my outside Coax line. 

Now understanding a little more about MoCa, I wanted to know if I need to enable MoCa on the router (10.x.x.x) in order to take advantage of the service or do I leave it disabled?

Thanks.
