Problem: Is there a way to make a post that I create, by default not translatable ?
Solution: You can achieve it by selecting ‘Not translatable’ for posts post type from WPML >> Settings > Post Types Translation as you can see in attached screenshot. https://cdn.wpml.org/wp-content/uploads/2019/03/3319201-not_translatable.jpg?x81497
