Does M.S. Supply Chain management could be STEM?

I have M.S. in management, supply chain management.

I am thinking to switch my major to engineering because I am not sure if I can get OPT extension. and I searched about it, some school says that MS-SCM is STEM, but I cannot see any real facts that someone who got OPT after graduating M.S. in management degree.

I wonder if this major could be STEM major to get OPT extension.
