What method exactly are you going to use?

If the argument is "X isn't encapsulated in the material" then surely removing the material should leave X intact. The other option is experimenting on what actually encapsulates X, but non materialists have a tendency to say what actually encapsulates X cannot be interacted with nor observed.

Yet they somehow claim that the non interactable non observable stuff is the actual mechanism by which things work. Which begs the question of how they reached that answer to begin with... since it's non interactable and non observable

Unless you got good reason to believe that there is more to it, you don't attach additional meta proprieties that no one can investigate, even from first principles (and this part is important, because it could be that the investigation methods simply haven't got there yet)
