nRF Connect SDK Gazell Support

We are starting a new Nordic-based project and are looking through the nRF Connect SDK 1.7.99 documentation (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/protocols.html).   Gazell is not shown as a supported protocol and don't see anything under proprietary protocols like in the nRF5 SDK.  

Does anyone know the status of Gazell in NCS?
