This is unlikely. There are many many theories of how dark matter could be accounted for with ordinary matter that we simply can't detect because our telescopes/etc aren't good enough.

Not all of these theories are completely excluded yet but most have very very thin margins of phase space left to explore (even when combining multiple explanations together). Every time a new telescope comes online we see the phase space diminish rather than hints towards first observations.

We are left with:

A) new particles that don't (or very weakly) interact with electro magnetic fields.

B) New theories of gravity.

C) New theories of the early universe that open up phase space previously thought closed to existing matter contributions

D) better instrumentation that sees actual contribution in the tiny phase space left to ordinary matter and ordinary physics

D is by far the least interesting of these options and so gets very little press. But it gets plenty of academic attention and you can be assured it is not being ignored by scientists
