[CA] [CA11] Disable broadcast only, possible?

[InsuredApple]

We've been told that we should install a "pirate switch" on our boat, which would disable the broadcasting of our AIS details, but still allow us to see other boats.

Someone mentioned that Raymarine may have an option for that, but I wasn't able to find it anywhere... here is what we have on our network:

Raymarine E22172 - i70 Multifunction Instrument
