How to set incoming mavlink telemetry data?

Hi all,

we are testing a copter swarm situation with several 3dr telemetry radio equipped with the multi-point firmware.
Is it possible to set which data the FC sends to the GCS in order to optimize the data flow disabling all the unused data (similar to what does the log_bitmask parameter for the flash datalogs)? There is some parameters to set in the FC parameters list or it is fixed in the firmware ?
Using 2 telemetry radios in mission planner “connection stats” tab report immediatly poor quality (5-7 %) and a lot of packet loss.

in MP config there is a telemetry rate section, change these values down to say 1
