To achieve this, we need a child theme.
This will also depend on which stack you're using at the moment. In case you are using Ethos stack, please copy,
_content-post-header.php from this folder:
wp-content\themes\x\framework\views\ethos to your child theme here:
wp-content\themes\x-child\framework\views\ethos. Then open the copied file and delete the following line:
<?php x_entry_navigation(); ?>
In case you are using Icon or Integrity, that function is added on the following files:
Same process, just copy the file on the same folder on your child theme and then delete the line of code.
Hope this helps.
