[Theme BLDR from Moderntheme] Remove featured image on post template

Man imma total noob but i could CSSing or phping a bit

Im tryin to stop the featured image from appearing on every single post.

here is my single.php

get_header(); ?>

<section id=”page-full-entry-content”>
<div class=”grid-pad”>
<div class=”col-1-1″>
<main id=”main” class=”site-main” role=”main”>

<?php get_template_part( ‘content’, ‘single’ ); ?>

<?php while ( have_posts() ) : the_post(); ?>

<?php bldr_the_post_navigation(); ?>

<?php
// If comments are open or we have at least one comment, load up the comment template
if ( comments_open() || get_comments_number() ) :
comments_template();
endif;
?>

<?php endwhile; // end of the loop. ?>

</main><!– #main –>

</section><!– page-entry-content –>

<?php get_footer(); ?>
