Additionally, we provide predictions for lepton flavor violating observables, the $\\mathcal{R}$ ratios in the decay channels $B_c \\rightarrow \\eta_c (J/\\psi) l \\nu_l$ and $B_c \\rightarrow D (D^*) l \\nu_l$ across the entire $q^2$ region. Our analysis is conducted within the Relativistic Independent Quark Model, focusing on the potential model-dependent aspects of these observables.
