Look at Bohm's interpretation of quantum mechanics and subsequent formulations for quantum field theory. Hidden variables are possible for quantum mechanics, they just necessitate that the Universe is fundamentally non-local, offering a possible explanation for quantum entanglement results. Von Neumann's rejection of hidden variables was not an absolute one but a conditional one; if the universe is local, then hidden variables cannot be invoked to explain the weirdness of the quantum world. Non locality opens the door to hidden variables.
