1. Install a free plugin called Code Snippets.
2. Go to Snippets > Add New > Functions tab.

3. Enter a title for your custom code, add the code, save the changes, and click to activate your code snippet. Example:

4. Clear WP Rocket's cache.

1. Go to the /wp-content/themes/your-child-theme/ folder.
2. Edit the functions.php file.
3. Add the code to the bottom of the file:
   

   

4. Clear WP Rocket's cache.

This approach requires proper (s)FTP access and a bit of experience in editing WordPress files.
