如何解决AddJsonOptions不包含SerializerSettings - .NET的定义

services.AddMvc()
    .AddJsonOptions(options =>
    {
        options.SerializerSettings.DateFormatString = "yyyy-MM-dd";
        options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
    });

JsonConvert.DefaultSettings = () => new JsonSerializerSettings
{
    DateFormatString = "yyyy-MM-dd",
    ReferenceLoopHandling = ReferenceLoopHandling.Ignore
};

public class CustomConverter : JsonConverter<DateTime>
{
    public override void WriteJson(JsonWriter writer, DateTime value, JsonSerializer serializer)
    {
        writer.WriteValue(value.ToString("yyyy-MM-dd"));
    }

    public override DateTime ReadJson(JsonReader reader, Type objectType, DateTime existingValue, bool hasExistingValue, JsonSerializer serializer)
    {
        if (DateTime.TryParse(reader.Value.ToString(), out DateTime result))
        {
            return result;
        }
        return existingValue;
    }
}

services.AddMvc()
    .AddJsonOptions(options =>
    {
        options.SerializerSettings.Converters.Add(new CustomConverter());
    });
