DJI FPV OSD support via MSP protocol on a latest stable Heli firmware

Hi all,
I have my quad running on master (EKF3) with DJI FPV MSP OSD support and its working okay.I tried to use master on my Heli (Kakute F7 Mini) but its not working great. I get all sorts of warnings like GPS glitch, Bad compass health etc. Also Yaw starts moving on its own while the model is sitting. I think its due to all kinds of sensor fusion on the latest builds using EKF3.

I tried to disable EKF3 on the master but looks like its not an option anymore.EKF2 is completely gone from the master:(

Is there any way to get latest stable firmware with DJI MSP support? Thanks.
