No we cannot reduce friction to zero because friction exists at even atomic levels too.

Friction cannot be reduced to perfect 0, if two surfaces are touching each other with some pressure. We could make that very small by using suitable methods. Without applying normal pressure, we cannot do any useful work in the world.
At microscopic levels, if we look at the surfaces of objects or floor or ice, we find that there are ups and downs. When two surfaces having small ups and downs rub against each other with some force normal to both surfaces, there is bound to be some friction ie., resistance force.
Also, there are intermolecular forces between the molecules of one surface and those of the other surface. That contributes to friction.
