How to make a method wait for the server response in java using Retrofit2?

Hello friends I have the following method that requests the server:

public MetaDataR metodo1(final String m) {
            Call<MetaDataR> call2 = new RetrofitConfig().getMetasService().getMetas(m);
            call2.enqueue(new Callback<MetaDataR>() {
                @Override
                public void onResponse(@NonNull Call<MetaDataR> call, @NonNull Response<MetaDataR> response) {
                    if (response.body() != null) {
                        MetaDataR iten = response.body();      ////Quero retornar "iten" para o metodo1()                       

                        }
                    }
                }

                @Override
                public void onFailure(@NonNull Call<MetaDataR> call, @NonNull Throwable t) {
                    // tratar algum erro
                    Log.e("Erro", "Erro ao buscar:" + t.getMessage());
                }
            });
            return null;
        }

This way it returns NULL every time. I need it to return the value that comes from the server, that is, that it waits for the request and returns "iten". Is it possible?
