I doubt this. Yes current *interpretations* of physical theories do suppose a material substrate, but only for having peaceful sleep (like the collapse non-answer in QM). Anyway, the theories does not presuppose it. They presuppose only mathematical structure and quantitative functor between those mathematical structure and numbers that we can measure in some communicable ways.
