We theoretically investigate the light-induced transition of kagome quasienergy spectrum into a Lieb-like under periodic driving fields. develop general framework for calculating renormalized hopping potentials, which is applicable to any two-dimensional lattice with arbitrary field polarizations. By implementing this on driven by linearly polarized light in off-resonant regime, we demonstrate that strength along specific bonds can be tuned zero. This control leads merging two inequivalent Dirac points Brillouin zone, governed parameters. from smaller bandwidth at value parameter. In addition, longitudinal optical conductivity measured Lieb and points, as suggested our calculation.
