Disclaimer: I might be wrong on any of the following:

The current Houdini Engine implementation does not evaluate Digital Assets at run-time. It is rather used to bake out things. So I doubt you would get much out of controlling the HDA via code. On the upside, you can bake some things from an HDA directly to blueprints with Houdini Engine in Unreal.

Aside from that I am not sure you can control an HDA from C++ or Blueprints in Unreal.

You would have to modify plugin code. The way to do this would be to create Houdini actor (which has Houdini component) and manipulate parameter functions on the component. But like DASD said, there's no direct way of doing it.
