No. A spontaneous reaction is one that will happen given enough time - it doesn't need any energy or enzyme to make it happen. For instance, the decomposition of carbonic acid (H2CO3) into water and carbon dioxide (H2O and CO2) is spontaneous. However, it can be reversed by an enzyme called carbonic anhydrase; it just takes energy.
