Can I configure Kong’s gRPC-Gateway plugin to return numeric enum values instead of strings?

[alikleit]

Looking at Kong’s gRPC-Gateway plugin config reference:
https://developer.konghq.com/plugins/grpc-gateway/reference/

By default, the gateway returns enum fields as strings in the JSON response.
Is there a way to configure it so that enums are returned as their numeric values instead?

For example, in Apache APISIX you can do this with the enum_as_value option:
https://apisix.apache.org/docs/apisix/plugins/grpc-transcode/#options-for-pb_option

Is there an equivalent setting or workaround in Kong’s gRPC-Gateway?
