Numerical results are reported on the discrete $\beta$-function of $SU(3)$ gauge theory with $N_f=12$ fundamental fermions in the gradient flow scheme. Controlled continuum extrapolation is performed for $s=2\;$ scale change with $c = \sqrt{8t} / L = 0.2$ targeting 3 tuned values of the renormalized coupling, approximately $g^2=6.0,\; 6.2\;$ and $\;6.4$. Contrary to a previous claim, no evidence is found for a zero of the continuum $\beta$-function.
