Can I remove the Download button on a Webscene details? I want to share a Webscene, but I would like to prevent the download .3ws file. It´s possible?
Unfortunately not, currently ArcGIS online doesn’t have a way to hide the download button on different item types.
There is delete protection offered which will hide the delete button but apps and files will always show the download button. Please add your request to ArcGIS Ideas - ArcGIS Online
