Certain VOCALOIDs do have a set personality and canon biography, which sometimes include their favorite and least favorite (or what is "thought" to be their weakness) genres. However, this does not affect the voicebank as a whole: that's entirely up to the power of a producer.

For example Yuecheng's biography says he is not good at rock genres, however, in the right hands, it can work (from what we can tell of his voicebank thought, it would be hard to do because of how aspirated and soft his voicebank is, plus we don't know if producers are allowed to directly tune him). UNI is another one an official favorite genre: EDM. Again, entirely up to the producers who can enforce that.

In terms of heavy metal, I feel like that also depends heavily on a producer's skill. Senjougahara Yousei is a djent producer (djent is a subgenre) and whenever he works with djent songs (because he is also known to work with pop and rock songs too), he usually has them growling but they're just not very strong.
