RBR/S50 & RBK853 + Switch

[matiernoII]

Currently I have an RBR50 network running.
I will be installing an RBK853 network at a new property that will also inherit the RBR50 hardware.

Is it doable to install a switch after a cable modem, then connect the two routers to the switch and have two networks running? Or am I limited to just one router?
The RBK would be a business network exclusively and the RBR would be a home/smart home network.

Thanks for your input.

Just 1 RBR router only. 

Netgear has set up a community forum specifically for the Orbi AX product.  Most of the people who watch that forum are more likely to have experience with Orbi AX and know how to work it better than those of us who follow this "general Orbi" forum.  Might be more likely to find someone who has a solution if the question is posted there:

Thank you.

No. Never. Not possible.  The modem expects to connect to ONE device with one MAC address.

If the "modem" is actually a combination modem/router, then 'Yes'.
