Disabling audio channel tone via API

I am testing possibility to replace current Savi W745 models with Savi 8240. We are controlling audio channel open/close in our code and we are also playing ring tones and other audio alerts from our code. Savi 8240 plays  a tone when the channel is opened. This can be disabled with the Plantronics Hub UI  (Settings ->  General ->  Audio Chnanel Tone) but we are not using it as we are using the Minimal Hub Runtime & COM Service .NET interop.  Is there a way to change this setting via the API or is there some other workaround?
