My ISP was not willing to do this for me, but they did give me the admin password for the device so I could change the SSID on the integrated WiFi. From there I was able to configure a bridge interface. Everyone is happy with this outcome.

Most of the time in my experience you can’t BYO ONT because it needs to be authed to the network and the ISP won’t do that other than for their own hardware. On the other hand I’ve never heard of being charged rental fees for an ONT.
