No, minimum drag is minimum drag, i.e., the bottom of the curve, i.e. minimum thrust required, i.e., best endurance (assuming fuel flow correlates with thrust). Since lift is constant across the speeds, the maximum of a term where drag is at the bottom (L/D), is at minimum drag.

The tangent point (best range) is to the right of that.
