System.Text.Json default DateTimeZoneHandling

In JSON.NET you can:
```
JsonConvert.DefaultSettings = () => new JsonSerializerSettings {
    DateTimeZoneHandling = DateTimeZoneHandling.Utc
};
```

Is there anything similar in `System.Text.Json`?
If there is not an option to set the default, can it be passed in manually?

Also, what is the default (`Local`, `Utc`, `Unspecified`)?
