How To Edit a Dashboard Template
Navigate to the "Templates" page, using the left menu on your Home page.
Next, click the Sections tab, at the top of the page. This was recently renamed from Dashboards, in anticipation of an upcoming feature release in 2023.
Select the section template that you'd like to edit by clicking the template name.
The section template editor will open, and you can then make any modifications to the dashboard section template in question.
