Two Combo Modem-Routers how to setup second as AP and/or MOCA (alien.top)

My current setup.

COAX ---> Xfinity Modem-Router ---> Wifi

I would like to repurpose a Netgear AC1200 Modem-Router as a range extender/MOCA/Switch to add ethernet ports to our home offices.

I know there are cheap range extenders but I prefer wired connections, and I already have the Netgear device.

Here's what I'm thinking.

COAX ---> COAX Splitter ---> Xfinity Modem-Router ---> Wifi

COAX Splitter ---> Netgear AC1200 Modem-Router ---> Wifi and Ethernet to Offices

Is this a ridiculous idea? I'm open to suggestions.

I would like to repurpose a Netgear AC1200 Modem-Router as a range extender/~~MOCA~~/Switch to add ethernet ports to our home offices.

Easy enough to test: Can you configure the Netgear modem/router in such a way that allows it to be hard-wired via Ethernet to your Xfinity gateway, LAN to LAN, such that any devices connected to the Netgear, wired or wireless, receive IP addressing from the Xfinity gateway? (typical manual configuration involves setting a manual IP for the AP, plus disabling DHCP services)

If the Netgear modem/router can't be configured to work in this way, it won't work if linked via MoCA, either. (Best case, you'll need a separate MoCA adapter to proxy the Netgear connection with the Xfinity gateway.)
