Is it possible (through hacking a config file or whatever, really) to disable certain profiles on specific devices from being enabled automatically when the device connects?

For example, my hands-free headset shows up as supporting both HFP and HSP on the N900, but I would like to disable HFP on that device since the phone likes to stream ALL audio all the time and ultimately run down the hands-free device battery very quickly.

Surely someone knows of a way to do this?
