Worse, nature isn't convinced, the first multimessenger observation of a binary neutron star merger effectively killed of the field:At the same time, a minority of scientists believe that dark matter is a mirage. They subscribe to an idea known as modified version of inertia, or MOND, which conjectures that on large scales, gravity acts differently than expected and this accounts for the observed rotations of stars and galaxies. But most experts aren't convinced of the need to take such a radical departure from known physics, which would also require modifications to our understanding of large parts of reality.

That unproven, unmodeled effect wouldn't work out since they are different phenomena.IMHO, Dark Matter is just a side effect caused by Dark Energy!
If you THINK, this view would easily explain:

In physical cosmology, the dark-energy-dominated era is proposed as the last of the three phases of the known universe, the other two being the matter-dominated era and the radiation-dominated era. The dark-energy-dominated era began after the matter-dominated era, i.e. when the Universe was about 9.8 billion years old.
