Honestly in Rome I imagine Nero would try to get the mob to do his dirty work, so to speak. Maybe a few fake confessions from "ringleaders?" I doubt there's more than a few tens of thousands of Jews in Rome - a larger population than the Christians of the same time period but definitely a small isolated foreign population that's totally at the mercy of any authorities who want to destroy them. I doubt Nero would deport them from Rome. After all, they're a less effective scapegoat if they're removed, no?
I mentioned Jewish support for the rebellions in Palestine to point out that I don't think there's sufficient Jews in this time period elsewhere to pose a meaningful threat. Those communities which exist elsewhere are isolated and disliked by their neighbors. After 70 CE the Jewish diaspora grows immensely, but at this point they're mostly a scattering on small groups, most of which I expect will seek to fly under the radar and hope to avoid persecution if it comes to war or a pogrom.
The mass deportation and enslavement OTL happened mostly in Palestine. Elsewhere, Jewish persecution tended to end in outright genocide or at least communal violence.
