Hi,
To achieve that, kindly do the following
- 
Setup a child theme - https://theme.co/apex/forum/t/setup-how-to-setup-child-themes/57
 
- 
Create file _content-post-header.php in wp-content\themes\pro\framework\views\ethos and copy the code below into that file.
 
<?php
// =============================================================================
// VIEWS/ETHOS/_CONTENT-POST-HEADER.PHP
// -----------------------------------------------------------------------------
// Standard <header> output for various posts.
// =============================================================================
?>
<header class="entry-header">
  <?php if ( is_single() ) : ?>
    <?php x_entry_navigation(); ?>
    <h1 class="entry-title"><?php the_title(); ?></h1>
  <?php else : ?>
    <p class="entry-title" style="font-size: 30px;">
      <?php x_the_alternate_title(); ?>
    </p>
  <?php endif; ?>
  <?php x_ethos_entry_meta(); ?>
</header>
- Add the code below in your child theme’s 
functions.php file. 
  function x_ethos_featured_index() {
    ?>
      <a href="#" class="entry-thumb<?php echo $index_featured_layout_class; echo $index_featured_size_class; ?>" style="<?php echo x_ethos_entry_cover_background_image_style(); ?>"> </a>
    <?php
  }
- Add this in 
Theme Options > CSS
 
.blog .entry-featured a.entry-thumb:before {
    display:none;
}
.blog .entry-featured a {
    pointer-events: none;
    cursor: default;
}
Hope that helps
