Never mind, after posting the question I figured it out and it actually wasn’t difficult at all. See here below:
<ul class="products">
<?php
$ids = get_field('pp_relation', 'option', false, false);
$args = array(
'post_type' => 'product',
'post__in' => $ids,
'posts_per_page' => 4,
'orderby' => 'rand'
);
$loop = new WP_Query( $args );
if ( $loop->have_posts() ) {
while ( $loop->have_posts() ) : $loop->the_post();
wc_get_template_part( 'content', 'product' );
do_action( 'iclicks_related_products_loop' );
echo '</div>';
endwhile;
}
wp_reset_postdata();
?>
</ul><!--/.products-->
