Hi TSConver
Thank you for reaching out. We are looking at a feature to "Disable" handlebar controls, this stems more from the GPS units that use the wonder wheel to navigate as well.
For the purpose of controller aux lights separately, though, you can set 1 set of lights up as auxiliary lights 1, and another as aux lights 2. With 2 sets configured as aux 1 and another as 2, you can operate them independently. If you have more than 2 sets though, I'd suggest setting the lights that require a lot of changes on the go, up as aux 1 or 2, and the other 2 sets as the other.
Kind regards
Ruan
