Not with the mainline batman-adv. But you can always add your own changes to
your code - making it incompatible with mainline batman-adv.
But I would highly recommend to handle authentication on a layer outside of
batman-adv.
Btw. "nonce" is a "number only used once". And you wrote here that the
firewall only whitelist one specific nonce. Which would imply that your nonce
is not used only once...
Kind regards,
Sven
