Delete _source field from existing index

Elastic Stack Elasticsearch

Is it possible to delete the _source field and reclaim the space that is
being used by already indexed documents?
The update mapping call : curl -XPUT
'http://localhost:9200/index_name/type1/_mapping' -d
'{"type1":{"_source":{"enabled":false},"properties":{...}}}'
doesn't reduce the index size

Once set, mapping can be changed only in a very limited way. For example,
you can add a new field, but you cannot delete any fields. So, in order to
disable source, you will need to delete the type that you want to modify
and reindex your data.
