In this work, we provide a promising way to alleviate the Hubble tension within the framework of Myrzakulov (Formula presented.) gravity. The latter incorporates both curvature and torsion under a non-special connection. We consider the (Formula presented.) class, which leads to modified Friedmann equations and an effective dark energy sector. Within this class, we make specific connection choices in order to obtain a Hubble function that coincides with that of (Formula presented.) CDM at early times while yielding higher (Formula presented.) values at late times. The reason behind this behavior is that the dark energy equation of state exhibits phantom behavior, which is known to be a sufficient mechanism for alleviating the (Formula presented.) tension. A full observational comparison with various datasets, including the Cosmic Microwave Background (CMB), is required to test the viability of this scenario. Strictly speaking, the present work does not provide a complete solution to the Hubble tension but rather proposes a promising way to alleviate it.
