I'm surprised that question has even been asked!
Why not ask something slightly more relevant to the operation of the airplane with respect to engine anti-ice. A very simple question that you would be (again) surprised to find that some are not aware...
Will the engine anti-ice system for an engine still work when the engine bleed air valve is closed?
Does happen...
