 Reject the measurement independence assumption. There are essentially two ways to do this. One is to suppose a common cause in the past that determines both experimental settings and experimental outcomes, as in the fanciful conspiracy story concocted by Shimony, Holt, and Clauser (1976). This sort of account has been called superdeterminism. Another avenue was suggested by Costa de Beauregard (1977), in a comment on the interchange between Bell and Shimony, Holt, and Clauser. Costa de Beauregard objected that the discussants were disregarding the possibility of retrocausality, a possibility that he had advanced earlier (1976). If causal influence from future to past is admitted, then, even if the settings are regarded as free variables, they could influence the state of the system at the moment of preparation, contravening the assumption that the preparation probability distribution be independent of experimental settings.
