Does the direct reduction of Fe(III) to Fe(0) occur?

The standard reduction potential of Fe(III)/Fe(0) is -0.037 V / SHE and that of Fe(III)/Fe(II) is 0.771 V.

Therefore, in cyclic voltammetry does the direct reduction of Fe(III) to Fe(0) occur near the -0.037 V?

Otherwise, does Fe(II) state must be go through so the reduction reaction does not happen?

Thanks a lot. It would be a great help to me :)
