Disabling EXCEL and CSV downloads of Scheduling feature

Hi,
In our QuickSight account, we have already assigned custom permissions to all our users, restricting their access to EXCEL and CSV exports. However, within the configured schedules, it can be seen that EXCEL and CSV downloads and attachments can be selected. Since we have “Authors” in our user base as well, they will be able to select the EXCEL and CSV downloads for their schedules and bypass the strong restriction that we have in our account.
There must be a way to disable CSV and EXCEL downloads entirely from the Schedules. It would have been really nice (and logical at the same time) if the custom permissions attached to the user were propagated across all features of dashboards and not only on direct exporting of the dashboards.
Can anyone please let me know how to disable EXCEL and CSV downloads from the scheduling feature?!
Thank you.

Hello Hatef,

At AWS, our roadmap is primarily driven by our customers. Your feedback helps us build a
better service. Since the said permission or feature to restrict format types during scheduling is not available , I have tagged this as a feature request.

Hope this helps.

Cheers,
