Well, on the object where this is relevant :-)

So on the property map of the conversion method, that is the one of

PropertyMap().set(IdentifiedObject::NAME_KEY, "Affine parametric 
transformation"),

Same here on the respective property map of each operation parameter.

so something like

Conversion::create
      (
          PropertyMap().set(IdentifiedObject::NAME_KEY, "Affine"),
          PropertyMap().set(IdentifiedObject::NAME_KEY, "Affine 
parametric transformation").set(metadata::Identifier::CODESPACE_KEY, 
metadata::Identifier::EPSG).set(metadata::Identifier::CODE_KEY, 9624) ,
          std::vector<OperationParameterNNPtr>
          {
              OperationParameter::create(PropertyMap().set(
                  IdentifiedObject::NAME_KEY, 
"A0").set(metadata::Identifier::CODESPACE_KEY, 
metadata::Identifier::EPSG).set(metadata::Identifier::CODE_KEY, 8623)),
              OperationParameter::create(PropertyMap().set(
                  IdentifiedObject::NAME_KEY, "A1")),
              OperationParameter::create(PropertyMap().set(
                  IdentifiedObject::NAME_KEY, "A2")),
              OperationParameter::create(PropertyMap().set(
                  IdentifiedObject::NAME_KEY, "B0")),
              OperationParameter::create(PropertyMap().set(
                  IdentifiedObject::NAME_KEY, "B1")),
              OperationParameter::create(PropertyMap().set(
                  IdentifiedObject::NAME_KEY, "B2")),
          },
