Herelink interference

I am using herelink air unit for video transmission and a 10 channel futaba transmitter for RC purpose. The futaba receiver is mounted on the top of the drone while the air unit is mounted on the bottom plate.
Is it possible for the air unit to create interference for the RC ?
(the flight controller is pixhawk cube 2.1 and futaba receiver is connected to RC_IN of the pixhawk. the SBus port of the air unit is unconnected)

The telemetry, video transmission, and rc are together packed in the 2.4GHz ISM band. Even if you are not using the sbus, the 2.4GHz band is still busy.
