How to disambiguate actors with the same name?

While scrolling through the credits of a documentary on my server, I was gobsmacked to learn that David Cameron, former PM of the UK, had played a small role in Mad Max. Fuck, he pulled of that mechanic's Aussie accent with no trouble, and at only age 13!

Obviously this actor just has the same name, but I can't find a way to tell jellyfin that this is someone else. It feels bad that I can either choose for this actor's biography to be overshadowed by the PM, or to cast him as himself in a documentary about a bunch of terrible people. Does anyone know of a solution?
