Hi Achraf,
You can do this and disable workflow.
Data Services Designer - Disable Workflow Step
Disabling objects (DF/WF) within a job, right-click and do .It could show a red X if disabled.
and also you can try.
When exporting objects, call out Disabled dataflows (highlighted somehow) in the Export screen
When exporting objects, display a pop-up dialog to warn the user of disabled dataflows, and give them the option to re-enable them before exporting
