The point is that there is no need to tweak GR. For example, [1] shows how properly accounting for GR and using rather detailed data about Milky Way allows to explain the rotational curves. But GR is complex enough to allow very different behavior depending on the initial conditions of galaxy formations. So it would not be surprising to see different scale of deviations from Newtonian mechanics depending on Galaxy history or age. [1] - https://arxiv.org/abs/1810.04445

The article cited from Wikipedia, https://arxiv.org/abs/1810.04445 , also pointed out that accounting for terms in the metric tensor related to rotation was essential to explain the rotational curves and not using them is simply unsound approximation.
