Pepwave Max BR1 - Using Google Wifi as router and AP

I have been using a Max BR1 at a remote Cabin/Shop for a few years but want to improve my Wifi coverage using Google Wifi Mesh networking. I want to just use the BR1 as an 4G LTE modem/bridge and let the Google Wifi handle all the routing for wireless and a couple of wired clients.

Besides turning off the wifi AP on the BR1 what else do I need to do?

Anyone have any advice?
