Are you aware of any visuals that show what the density distribution of DM looks like to fix the expected the rotation curves for some example galaxies?

DM distribution is different for every single galaxy, and so can only be fit to the galaxy's rotation curve after observing it. In contrast, MOND successfully predicts rotation curves a priori using only the visible matter.
