Currently, it is established that valley polarization in altermagnetism remains largely insensitive to spin-orbit coupling and spin. Here, using Cr$_2$S$_2$ as a case study, we investigate the mechanism through which an external field modulates valley polarization in altermagnetism. This effect arises from the external field's disruption of diagonal mirror symmetry $M_{xy}$, consequently inducing valley polarization within the material.
