NEST/Elasticsearch.Net version: 6.0.2

Elasticsearch version: 6.2.2 /6.1.2

I want use a partial update  
\_client.Update\<T, P\>(docPath,  
f =\> f.Doc(partialDocument).Index(\_indexName).DocAsUpsert().Routing(routing)  
)

The partial document have a property dictionary that is not serialized when values are null.

How to handle the nullvaluehandling without change the global settings connnection?

The documentation in  
[https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/custom-serialization.html](https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/custom-serialization.html)  
is not exhaustive.

Thanks
