Hide comments and attachments on calendar embedded on dashboard


I am creating a customized dashboard for all of our stakeholders to view events and trade shows within their region.

The main file is used by my team to plan all of these events and trade shows, so it has a lot of comments and attachments that I do not want to share with stakeholders. When I created a report to show the list of events, I was able to select the columns to display and hide the comments and attachments. However, when I embed the calendar using a Web Content widget, my end users can click on the calendar events and see the selected columns (which is perfect) along with all of the comments and attachments. Is there any way to hide comments and attachments from my end user?

I do not have Calendar App and my request to get it has not been approved. Any ideas for a workaround?
