SuperJSON is wrapping results in type with keys "json" and "meta"

How can I modify the transformer in SuperJSON library to only return the "json" property and ignore the "meta" property during serialization? The current behavior of the library wraps the results in the SuperJSONResult interface, but I want to access only the "json" property after serialization.

interface SuperJSONResult {
    json: JSONValue;
    meta?: {
        values?: MinimisedTree<TypeAnnotation>;
        referentialEqualities?: ReferentialEqualityAnnotations;
    };
}

interface SuperJSONResult {
    json: JSONValue;
    meta?: {
        values?: MinimisedTree<TypeAnnotation>;
        referentialEqualities?: ReferentialEqualityAnnotations;
    };
}

This is my current code

const t = initTRPC.context<inferAsyncReturnType<typeof createContext>>().create({
  transformer: {
    serialize: SuperJSON.serialize,
    deserialize: SuperJSON.deserialize,
  },
});

const t = initTRPC.context<inferAsyncReturnType<typeof createContext>>().create({
  transformer: {
    serialize: SuperJSON.serialize,
    deserialize: SuperJSON.deserialize,
  },
});
