Related stories are enabled by default in the following two story templates:
1. Hero Priority left
2. Headline Priority

You can remove the related stories section by switching the story template to one of the following layouts (these do not include related stories):

• Hero Priority Center
• Headline Overlay Priority
• Headline Hero Priority
• Hero Vertical Priority

Please find the steps to change the Layout

1. Log in to Page Builder.
2. Open the Page dropdown (top-left corner).
3. Select the Story Page and the Story Type you want to modify.
   
4. On the story card, next to the image, you will see two icons: Layout and Settings.
5. Click the Layout icon.
6. Choose any layout that does not include related stories & publish the changes.
    

Note: You will need to apply the same update to other story pages individually (e.g., Video Story, Photo Story, Live Blog, Listicle, etc.) if you want to remove related stories from those templates as well.
