Is that true that the only condition Ff can be zero on gravity influence, is when the mass become completely static?

The formula of friction force is Ff = μN can also be defined as Ff = μ.m.g One of my friend say that mathematically, that equation tell us that when there is a gravity force, Ff can't be zero assuming that there is no zero μ Is that true? While on static condition I will say that even...
