1. Add a wrapper CSS class around the Content Block, e.g. hide-on-details
. Then, in the Details view of the dynamic module, define this class as display:none;
3. Implement a custom Content Block widget - since Feather widgets are open source, an own version of the Content Block widget might be implemented by applying minor modifications to reach the goal in mind:
4. Use a Sitefinity page instead of auto-generated ones - that will give the developer control over what's rendered on the Details page.
