Multi-touch for TVos/Siri Remote

Hi board, I've been searching high and low and am trying to get a definitive answer. Is there a way, either through Unity or through native Swift code, to implement or access multi-touch functionality (pinch to zoom, for example) for the Siri remote touchpad? It looks like it is not really supported, but I can't find a document that says clearly yes or no. Any insight or methods people can provide? Thanks so much
