Sure. Simplest way is set up some tracks in your DAW. Stick some FX on them.

Route the inputs of your interface to these channels. Route the DAW channel outputs to the outputs of your interface.

Board aux send ---> converter/interface -->DAW ---> converter/interface ---> aux returns or channelstrips.

You may have to play around with your DAW's buffer settings to get the latency as low as possible.
