How to use custom DateTimeConverter for selected endpoints?

public class DateTimeConverter : JsonConverter<DateTime>
    {
        public override DateTime Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
        {
            var dateTime = DateTime.Parse(reader.GetString());

            return dateTime.ToUniversalTime();
        }

        public override void Write(Utf8JsonWriter writer, DateTime value, JsonSerializerOptions options)
        {
            writer.WriteStringValue(DateTime.SpecifyKind(value, DateTimeKind.Utc));
        }
    }

.AddJsonOptions(options =>
{             options.JsonSerializerOptions.Converters.Add(new DateTimeConverter());
});
