Road FBX model, and map matching problems

The road model data exported by RoadRunner can only be matched with the map with the Global mode of MapTyoe, but I want to be matched with the Local (plane mode). Is this feasible? Or can the FBX model of the road I process only be matched with one of the modes?

string wkt = "COMPD_CS[\"CompoundCS\",PROJCS[\"unnamed\",GEOGCS[\"WGS 84\",DATUM[\"WGS_1984\",SPHEROID[\"WGS 84\",6378137,298.257223563,AUTHORITY[\"EPSG\",\"7030\"]],AUTHORITY[\"EPSG\",\"6326\"]],PRIMEM[\"Greenwich\",0,AUTHORITY[\"EPSG\",\"8901\"]],UNIT[\"degree\",0.0174532925199433,AUTHORITY[\"EPSG\",\"9122\"]],AUTHORITY[\"EPSG\",\"4326\"]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"latitude_of_origin\",30.03097934573528],PARAMETER[\"central_meridian\",121.2600064055433],PARAMETER[\"scale_factor\",1],PARAMETER[\"false_easting\",0],PARAMETER[\"false_northing\",0],UNIT[\"metre\",1]],VERT_CS[\"EGM96 geoid height\",VERT_DATUM[\"EGM96 geoid\",2005,EXTENSION[\"PROJ4_GRIDS\",\"egm96_15.gtx\"],AUTHORITY[\"EPSG\",\"5171\"]],UNIT[\"metre\",1,AUTHORITY[\"EPSG\",\"9001\"]],AXIS[\"Up\",UP],AUTHORITY[\"EPSG\",\"5773\"]]]";

_arcGISMap.OriginPosition = new ArcGISPoint(_gisLon, _gisLat, _gisHeight, new ArcGISSpatialReference(wkt));

The wkt in this code is the parameter obtained when RoadRunner software processes the model data. Can I correspond with the map whose MapType is Local by using it in this way? Please answer my doubts, thank you

_arcGISMap.OriginPosition = new ArcGISPoint(_gisLon, _gisLat, _gisHeight, new ArcGISSpatialReference(wkt));

Using this wkt file, I changed the map mode to Local, which still did not match the road model data exported by RoadRunner

Can the difference between these two projections be reflected in Arcgis for unity
