Go to Portal Tables.
Click on the table where you want to remove the thumbnail.
In the Views section, go to Default View Settings.
Make sure the View Type is set to either List, Gallery, or Kanban. If your custom view doesn’t inherit the default view settings, adjust this in the custom view settings.
Scroll down to find the Thumbnail setting.
Select No Thumbnail.
I do not want to show a thumbnail when using List, Gallery, and Kanban as layout.
