wifi calling without upgrading to MM?

[cerps]

Is there any way to get wifi calling on our AT&T G4's without upgrading to MM? I'd prefer to stay on LP so I can root and also so I can use my bluetooth heart rate monitor and other sensors. 6.0 has bugs that make bluetooth Low energy sensors not work correctly. There is a fix in 6.0.1 but my understanding is the G4 is still on 6.0. Wifi calling would be great because I encounter poor signal at work.

It seems to be part of the firmware, but I didn't know if there was a setting somewhere like the build prop file to change or something I could sideload to enable wifi calling.

Hopefully this can be done, I also am still rooted on LP mainly for tether. I would like the wifi calling feature, but don't want to give up another one.

It look like the update makes the wifi calling toggle appear up in the notification panel. I don't know if it adds any code. I wonder if it's buried somewhere in the firmware already? I thought maybe I could find/toggle it by creating a shortcut in Nova Launcher like I did with the permission manager for Access Lock. I couldn't find one although I don't know what I'm exactly looking for. there are settings buried in there with vzw in there so maybe it is buried in there.
