There is some evidence that it can help against self inoculation and immune response to an existing infection

From what I’ve seen, it’s been shown to be effective against existing infections, as well as preventing it from progressing to cancer.

I can't find anything about this, do you have any papers?

I don't think it's been tested in studies, but I can offer that I had hand warts for 7 years until I got the HPV vaccine, and the hand warts suddenly disappeared after dose 2.

HPV functions by cloaking itself from your immune system. The reason why treatments like freezing work is not by removing the HPV -- it's by stimulating your immune system to look at the area around the wart. Then your immune system can get past the cloaking, and recognize the HPV, and then it destroys it.

So functionally, it makes total sense that the HPV vaccine would clear existing infections, and anecdotally, lots of patients (such as myself) have seen HPV clear after getting the vaccine. It's a shame that our bureaucracy doesn't have the incentives to run the studies to acknowledge it institutionally.

From my understanding most vaccines have never been compared against placebo trials, but would be happy to be proven wrong, e.g. if you can find a study on HPV vaccine.
