Did you check the dashboard properties option? there you can uncheck the export option for specific dashboards
The short answer is "no you can't".
The export full dashboard in Excel is a generic privilege you have or not and can't be configured by dashboard. The only option you have is, as SunilSharma, suggest to allow / disable the export object by object (so analysis by analysis).
But the generic one you can't really configure it: you can or not, in the whole system.
Hi Ceresa, Thanks for the response. Sunil's option will not remove export entire dashboard option, it can be done for Print PDF/HTML.
That's true, Sunil option is not going to remote it from a give dashboard just because, as said, it's a general setting: if you have the privilege it's always there.
Sunil was giving you an alternative in case you decide to disable it for everybody and then want to enable some exports links on few pages / dashboards / analysis.
