Hi @gas1123,
Before we proceed further, would you share why you’d like to remove the “Take this course” button? Perhaps there is another way to achieve what you’re trying to do here.
I ask, since “Take this Course” is one of the core Sensei blocks — Lesson Actions block — which is designed to be essential part of Sensei’s functionality. Deleting the block may work as a one-off cases, but if you’d like to remove the button for all courses, you’ll need to do some developer-level customization (which is outside the scope of our support).
Here is some information about how Sensei course layout is displayed, and how Sensei Blocks work:

—
Instead of removing the essential functionality (and causing potential problems), we’d like to find suitable solution for you if possible.
For example, if you’d like to remove the block because you don’t want people to enroll in courses, you can disable “Anyone can Register” option in Wp-admin > Settings.
For another example, if you’d like to make the course available to all users (i.e, without taking the course), you can make the Course “open access” for guest students: https://senseilms.com/documentation/courses/#open-access-guest-students
I hope that helps! Let us know what you think.
