Disable on Custom Post Types

I would love to be able to not show the notification on CPT pages and I’ve tried the following to see if it would work but it does not, ( !is_page(array(‘my-account’, ‘my-courses’,)) || !get_post_type() === ‘lessons’ ). It would be much much easier to apply a custom post type than to have a huge array of CPT post IDs. Is there any way this can be accomplished?
