You could set up graphic overrides, save a 3D view in your View Map with those GO settings applied and publish that to BIMx.
This is a bit crude though, as it will override entire elements. For example, if you override a brick texture surface with a white paint, it will apply the white paint to all sides of a wall that has the brick texture anywhere.
You can also switch to white model in the BIMx app or hidden line, etc. These will simplify the way BIMx shows the model, without needing to change anything on the ArchiCAD side of things.
