What about in the classical Kaluza theory described at https://en.wikipedia.org/wiki/Kaluza–Klein_theory ? It seems from the description that it shows a way Maxwell's equations could be derived from spacetime curvature in the same way as gravity (albeit by adding an extra spatial dimension, which Klein postulated might be rolled up), I wonder how it accounts for positive vs. negative charge and if there is still an equivalence principle where it approaches Minkowski spacetime in the small-scale limit.
