This code got what I needed. Make sure to add the #hide_this_div to the whatever you want to hide and change the ‘ACF-field-name’ in this code to your field name. You can change the ‘post’ to any CPT.
add_action('template_redirect', 'hide_disabled_blocks');
function hide_disabled_blocks() {
global $post;
// get dynamic project id
$post_id = $post->ID;
// get value of true-false field in each post
$hidediv = get_post_meta($post_id, 'ACF-field-name', true);
if is_singular( 'post' ) :?>
<style type="text/css">
<?php
// if "ACF true-false command" is false, hide the Div ID
if ( ($hidediv == '0') || (empty($hidediv)) ): ?>
#hide_this_div { display: none; }
<?php endif;
?>
</style>
