I'm not aware of any "proprietary modulation", and I doubt it's possible
least not while using an AP at the same time. You can look into 5/10 MHz mode
or do other quirks if mesh is the only thing running on your module though.

Thanks a lot for your reply.
With ath9k chip and ath9k driver, do you think it is possible to use
"proprietary modulation" (slightly modified), so wireshark + wlan in
monitor mode won't be able to detect wireless frames batman-adv network
