Hi,

I advise doing this in your own child theme:

You’ll have to modify the /activity/index.php file. In there you can change your activity stream loop to just return status updates, and you can also remove the dropdown filter.

This page gives some guidance on modifying the activity stream loop, including the filter you’ll need just for status updates:
