BRD_ALT_CONFIG for omnibus f4 pro v3

Hi,
I use ardurover(v4.0:boat) using omnibus f4 pro v3.
I am going to use a mavlink-wifi bridge telemetry on ardurover.
I can read on manual that it was possible to use BRD_ALT_CONFIG(0 →3) to configure second telemetry using rssi(tx)& pwm5 pads(rx).

Will you please teach me following question.
I can’ t find BRD_ALT_CONFIG on ardurover.
I am looking for it on full parameters list (on latest qgroundcontrol) but it is not there.
Can’t I use it on ardurover?
(But I can find it on arduplane + omnibusf4 v2)

Thank you…

I know this is an old thread, but for anyone else looking for the solution.
Using Mission Planner 1.3.79 build 1.3.8375.24878 ArduRover V4.2.3

The setting is found in Config - Full Parameter List - BRD_ALT_CONFIG . I changed the value from 0 to 3.

I’m running a BN-880 GPS (tx6,rx6) J10 / compass (scl,sda tx3,rx3) J10 with Spektrum satellite receiver (DSM2 tx1,rx1) J8 and a SIK 915MHz telemetry link (tx4,rx4)rssi pad, pwm5 pad.
The serial settings that I have are -

Serial 1 - Usart1 - Spektrum receiver
SERIAL1_BAUD 115
SERIAL1_OPTIONS 0
SERAIL1_PROTOCOL 23

Serial 2 - Usart3 - N/A

Serial 3 - Usart6 -GPS
SERIAL3_BAUD 38
SERIAL3_OPTIONS 0
SERIAL3_PROTOCOL 5

Serial4 - Uart4 - Telemetry
SERIAL4_BAUD 57
SERIAL4_OPTIONS 0
SERIAL4_PROTOCOL 2

I hope that helps someone in the future.
