Qgroundcontrol tbs crsf telemetry wifi


i’m working on a dolphin vtol under px4 . i saw a funny optional : the possibility of transmitting the flight information to qgroundcontrol with the tango 2 ( wifi 2,04 option).
i also saw this PX4-user_guide/en/telemetry/crsf_telemetry.md at f07827565054f90505f91b6ae80a0f6af1246b71 · PX4/PX4-user_guide · GitHub

unfortunately i’m not able to modify the vtol firmware … is there a possibility to get it modified ?
another demand : if somebody uses that option : does it work ?
thanks .
