Handler for Fibaro Siren

My Fibaro siren connects fine using the Aeon siren handler. What the handler will not do however, is give me the option to operate the lights only - siren muted. Appreciate some help on this one please.

I saw a similar post a few days ago:

I know this is a different device, but the solution could very well be similar. I would check the device developer docs to see if you could do something similar.
