Yellowbrick clustering visualizers currently work with centroidal clusterers. You can read more details here: http://www.scikit-yb.org/en/develop/api/cluster/index.html#clustering-visualizers.
It looks like KModes and KPrototype are not part of core scikit-learn, but if they implement the scikit-learn estimator interface (which they appear to do) there's a good chance they'll work with Yellowbrick. Maybe you can try it and see if it works . We would be interested in what you find out.
