Hi,You can refer to
https://experienceleague.adobe.com/docs/experience-manager-65/assets/managing/download-assets-from-aem.html?lang=en
and try to disable the asset download servlet. If you don't want to show
only the download button, you can try to add deny permissions for the
download node (or preferably higher level hierarchy) as per your user
group. Eg. deny for
/libs/dam/gui/content/assets/jcr:content/actions/selection/download
