How to set disableChaining like streaming multiple INSERT statements in a StatementSet ?

[hjw]

Hi,
I create a StatementSet that  contains  multiple  INSERT  statements.
I found that  multiple  INSERT tasks will  be organized in a operator chain 
when StatementSet.execute() is invoked.
How to set  disableChaining like streaming multiple INSERT  statements   in a 
StatementSet api ?


env:
Flink version:1.14.4
