Superdeterminism is a loophole in Bell's theorem that allows local hidden variables, so there could just be a fully deterministic theory that determines everything, including your detector settings in advanced. Classical physics has generally assumed that we at least have free choice to choose what to measure. If we don't, we can trivially retain classical gravity
