I am not aware of any superdeterministic theory that can explain the violation of Bell's inequality. They only argue that a violation of Bell's inequality is not impossible in a superdeterministic local hidden variable theory (but no such theory has been formulated). I suspect this is why Hossenfelder just knocks down a few strawmen in her video on superdeterminism [1], instead of addressing the elephant in the room (experimental violations of Bell's inequality).

Everyone agrees that superdeterminism can evade Bell's theorem, the key is making this evasion as plausible or more plausible than accepting many worlds or the absence of counterfactual definiteness. Given so little effort has been expended in this direction because of incorrect assumptions of superdeterminism, it's not surprising that these models are still rudimentary proofs of concept, but the notion that Bells' theorem is some insurmountable obstacle is just incorrect.
