This paper shows that a noncovariant, metric-only action built from the quadratic connection part of the Ricci scalar can yield MOND in the nonrelativistic limit, and identifies it with fixed-gauge BIMOND and f(Q) gravity.

abstract
We show that treating gravitation as a thermodynamical theory leads to the modified Newton dynamics (MOND) equations if one takes into account the Hubble's expansion. Then the universal MOND acceleration a0 is exactly twice the product of the light velocity c and the Hubble constant H. No dark matter is needed for the description of the galaxy rotational curves as well as for the accounting for the additional gravitational lensing at large distances.

Noncovariance at low accelerations as a route to MOND
This paper shows that a noncovariant, metric-only action built from the quadratic connection part of the Ricci scalar can yield MOND in the nonrelativistic limit, and identifies it with fixed-gauge BIMOND and f(Q) gravity.
