Since commit d6097b8d5d55 ("crypto: api - allow algs only in specific constructions in FIPS mode") there's support for using spawns which by itself are marked as non-approved from approved template instantiations. So simply mark plain ghash as non-approved in testmgr to block any attempts of direct instantiations in FIPS mode.
