How to set flat file custom property EscapeQualifier to true

In SSIS, a flat file destination has a custom property EscapeQualifier. It is defined as:
When text qualifier is enabled, specifies whether the text qualifier in the data written to the destination file will be escaped or not. The default value of this property is False.
I've tried to import an SSIS package into BIML to see how it would be coded; but that didn't work.
Also tried
FlatFileDestination
  DataFlowOverrides
    Component
       Properties
          Property PropertyName="EscapeQualifier" (value) true
without success.

Any ideas how to implement this in BIML?
