Xfinity gateway MoCA behavior in bridge mode

Hi, I recently got a new Xfinity One modem and it supports MoCA. I run my own router in the 192.168.x.x address domain and do not want to change the configuration of my network so I plan to reconfigure the Modem to operate in "Bridged" mode. My understanding is that in this mode, it would take any DHCP requests and pass them to the router.
However the option to enable MoCA is disabled while in “bridged” mode.

My question is what happens to your embedded MoCA when running in bridge mode? I am assuming that the sequece of events goes:

DHCP request->ethernet--->moca_adaptor-->modem-embedded-service->bridge->router;

and for the return trip:

router->bridge->embeded Moca service->moca_adapter->ethernet->host requsting DHCP

can you please clarify how to use the embedded MoCA config while maintaining my own router/WiFi?

I'm not a Comcast employee, but AFAIK the MoCA function is disabled when the gateway device is put into bridge mode.

In bridge mode, the combination cable modem / router gateway devices become plain vanilla cable modems like any other ordinary modem. They no longer have a router component. It's by design.

MoCa doesn't work when Comcast takes their MoCa network controller off line, because MoCa only work on mesh topology.

They took off their network controller on my network segment too, couple of month ago.

I don't see their network controller in mesh diagram on their XB7 gateway anymore.
