Use the [EndpointOption](https://docs.cloud.google.com/cpp/docs/reference/common/latest/structgoogle_1_1cloud_1_1EndpointOption.html) when initializing the client library to change this default.

For example, this will override the default endpoint for `apikeys_v2::ApiKeysClient`:

      // This configuration is common with Private Google Access:
      //     https://cloud.google.com/vpc/docs/private-google-access
      auto options = google::cloud::Options{}.set<google::cloud::EndpointOption>(
          "private.googleapis.com");
      auto vpc_client = google::cloud::apikeys_v2::ApiKeysClient(
          google::cloud::apikeys_v2::MakeApiKeysConnection(options));
