The answer to your question is yes.... BUT....
I have a setup at my location to do exactly what you are asking.
YAAC itself doesn't have this capability (to my knowledge) but it can connect to a iGate on the network.
I have a Raspberry Pi running Raspbian with VNC viewer and secure shell running on it for remote access as it is headless.
On the Pi I have direwolf running automatically on startup with it's config file in /etc/
Direwolf is running as a iGate for APRS
AGWPort and KISSPORT are set and enabled
Via YAAC I enabled a KISS-over-TCP port and pointed it to the static IP address of my iGate.
With this setup my iGate acts as my transceiver for YAAC running on my local machine.
Hopefully that points you in the direction you're asking for.
