We adopt the principle of maximum conformality (PMC) to set the renormalization scales for those decays. After applying the PMC scale setting, we determine the optimal renormalization scale for the $B_c\\to\\eta_c(J/\\psi)$ transition form factors (TFFs). Because of the same $\\{\\beta_0\\}$-terms, the optimal PMC scales at the NLO level are the same for all those TFFs, i.e. $\\mu_r^{\\rm PMC} \\approx 0.8{\\rm GeV}$.
