TBS Crossfire via mavlink with ads-b - response lag

Hi I have strange issue. I have connected tbs crossfire via telemetry1 port (mavlink protocol), and its working properly - Im using this setup for all my boards, mostly on matek wings but now I would like to use with Orange Cube.

But, when I enable mavlink for serial5 (ads-b) I have big delays for response from my radio (crossfire with mavlink). Any idea what can I set to fix this ? I tried to find port priorities or something like that.

Thanks for any ideas.
