The way I read it, Xfinity is touted as a "wonderful solution to everything". They provide a web portal to configure and control the myriad of services: https://www.xfinity.com/support/articles/xfi-app-and-portal Gosh, Xfinity even provides WiFi "extender pods" (sort of like an Orbi system).
My guess is that by logging into your Xfinity account you can do things like turn off the Xfinity WiFi.
Have no idea if the Xfinity can be placed into "bridge mode".
If it cannot, then the easiest solution is to (a) disable the Xfinity WiFi and (b) attach the Orbi in Access Point (AP) mode.
