I’d say, come up with a model, see if it explains known physics, then see if it predicts previously unobserved evidence. If your model does that, it’s a useful model of physics!
Yes, of course, because metaphysical claims are still claims, and some of them are clearly false because they contradict available evidence. However, once we have a metaphysical claim that can’t easily be disproven, now we have a claim that’s up against the limits of our ability to know, and an important aspect we’re leaving out here is that metaphysical claims make claims about the unknowable (otherwise they would be physical claims, not metaphysical ones).
The best outcome a metaphysical claim can hope for is “not yet proven wrong”.
