unfortunately i can't, and it's unrealistic that any government would force them to do so, that's why bitcoin came around, and even if they did publish it, there is no way to make sure they're actually using this very protocol to exchange transactions, plus it doesn't eliminate transaction censorship and surveillance
They do, just not in a very public way to people outside the cryptography community, and there's no audit of course on the implementations. All of Visa's protocols are in some form in the papers published by Visa Research.
