Maybe not.

My personal view on this problem:

galaxies are not held together by gravity and there is no need for
gravity, because the galaxies are not rotating in their own frame of
reference.

But seen from a comoving position from within that galaxy, the

Rotation is absolute. If a galaxy is rotating, that it is rotating can
be detected either from within or without the galaxy.
'Absolute' is a dangerous term in cosmology, because relativity says, that space itself is not absolute.
Rotation is absolute in that a rotating frame has a pseudoforce, and Newton's Laws don't hold. This cannot be compensated by assuming the frame is not rotating and the rest of the universe is rotating in the opposite direction.
