The way to look at DCS-BIOS is if it is related t the plane / cockpit, then you should be able to interact with it, if it is related to the sim, then probably not. I stand to be corrected on this, but from my limited knowledge it is how I understand it.
I am sure with some clever code you can get it to do anything.
Download DCS-BIOS, and then in the docs folder is the control-reference.html file. It lists all the commands you can use, that way you can search thru it to see if what you are trying to do is there.
