Take a look at the "-pkeyopt" option of pkeyutl(1).  I believe these are the
same options.

If we ignore key generation parameters, all I'm finding is:

   dh: dh_pad
  rsa: rsa_padding_mode
  rsa: rsa_pss_saltlen
  rsa: rsa_mgf1_md
  rsa: rsa_oaep_md
  rsa: rsa_oaep_label

And "dh_pad" many not be applicable to dgst(1).
