It's unclear what your reason is for believing there's an actual, specific, restriction, in force against these specific engines.
If you haven't read many of these types of regulations before, a general category that matches means very little.

Consequently, it's likely other clauses otherwise targeted to military-only powerplants might apply to the Olympus 593, despite being a civil certified engine, simply by virtue of also being supersonic.
