You can also set this up so that every Elementor page is set to Contained instead of Full Width. The updated code is below the Full Width code.
NOTE: be SURE to have only ONE snippet activated if your create a new one for this instead of modifying the existing Full Width code!
If you are sure that every page you are going to create with Elementor will have the Disable Elements > Content Title disabled and the Page Builder Container set to Full Width, then add the code below to a Code Snippets snippet. Set the snippet to ‘Run snippet everywhere’. Pages or posts created with the WordPress editor will not be affected.
Thanks to Tom Usborne from GeneratePress for this.
