Does firmware update for Cam Pan 2 block RTSP or Dafang Hack firmware?

So I bought a Cam Pan 2 with the goal of using it with Dafang Hacks or RTSP firmware + Homebridge/HomeKit as I was turned off by the reports of the stock firmware phoning home to China (which AFAIK was never resolved?).

That said, I'm not sure I'll get the chance to setup everything before an upcoming vacation and the WyzeCam app works OK but keeps nagging me to upgrade the firmware. Knowing how these things tend to go, I was wondering if anyone has insight on whether the latest firmware blocks custom firmware or even the Wyze RTSP firmware that uses a similar programming process.
