ArcGIS Map Service enable Textual Query but disable Geometry return in ArcGIS Server Map Service Setting

[KLEric]

Dear Sir/Madam,

I would like to know is it possible to have a setting in ArcGIS 10.4 Map Service that when using JavaScript API to 
identify (i.e. esri.tasks.IdentifyTask). ONLY the textual attribute is return. no matter how to script the client-side script.

Actually, we need the map service to have this behaviour , so as to prevent hacker to get the geometry by using JavaScript in clientside. while textual attribute is open, the spatial polygon want to be see on our map only.

Is there any way to do so on particular map service?

Thank you very much for your help
Best Regards
Eric Yuen
