There's conformal gravity, which replaces the Einstein field equations with ones derived from a conformally invariant action. Like MOND, this allows you to fit rotation curves nicely without invoking dark matter, see eg [1][2]. [1] https://arxiv.org/abs/1211.0188 (2012) [2] https://arxiv.org/abs/1812.03152v3 (2018)
