Hello.
Thanks for reaching out to the Microsoft Community.
Regarding your question, currently SharePoint doesn't offer a direct built-in feature to see exactly how many times a document has been downloaded. However, you can track activity on documents, including views and edits, using the built-in file activity reports.
See further information about this, here: View usage data for your SharePoint site - Microsoft Support.
In the file activity reports, you can see activities like views, edits, and who accessed the document, but download tracking specifically is not detailed separately from views.
If you have further questions let me know.
Best Regards,
Daniel Coy
