Changing baseSchemaPrefix :n4sch to custom name "azdt

I have used call n10s.graphconfig.set( ) command to update neosemantics configuration

For some reason baseSchemaPrefix is not updating. rest of the parameters are being updated.

here is the command used

call n10s.graphconfig.set( { keepLangTag: true, handleVocabUris: "MAP", handleRDFTypes: "LABELS", handleMultival: "ARRAY",keepCustomDataTypes: true , baseSchemaPrefix: "azdt",baseSchemaNamespace: "" });

I want to use make baseSchemaPrefix: "azdt".

Please let me know, how this can be updated
