To further my above post I called and talked to shaw. No accessible Bridge mode on this modem.
They walked me through setting it up on IP passthrough and I had already disabled Radio so that step wasn't needed on my end. According to the tech I spoke to all Shaw does to "setup" bridge mode is activate your second IP and then turn on IP passthrough and disable Radio. If you previously had a modem bridged with them your second IP is already active so you can enable passthrough by yourself. On the screen it will ask what port you want to enable passthrough for, pick whatever you want just know that they are labelled 1-4 with 1 being the closest to the coax input.
Slight increase in speed on IP passthrough of a few mbps, ran the test 5 times and this was the lowest. All tests on WiFi
