Exclude a specific taxonomy name - php

Question

So I'm using wordpress and ACF. I created a CPT called products and a custom taxonomy named product_types. I have a loop that displays all product_type sections and each section contains products tied to it. So I'm looking for ways to easily filter new products or popular products thats why I come up with adding a dedicated category for it but I dont want it to exclude it from my post loop. pls see img attached
enter image description here
Here's the code I'm working with atm
<?php
$cpt_name = 'products';
$taxonomy_name = 'product_type';
// Retrieve the terms in the above taxonomy.
$terms = get_terms( $taxonomy_name );
if ( empty( $terms ) || is_wp_error( $terms ) ) {
return;
}
echo '<div class="products-group">';
foreach( $terms as $term ) {
echo '<div class="products-category">';
echo '<h2 class="title-category">' . $term->name . '</h2>';
$args = array(
'post_type' => $cpt_name,
'tax_query' => array(
array(
'taxonomy' => $taxonomy_name,
'field' => 'slug',
'terms' => array( $term->slug ),
),
),
'posts_per_page' => -1,
'category__not_in' => array( 30 ),
);
$query = new WP_Query( $args );
echo '<div class="products-list">';
while ( $query->have_posts() ) {
$query->the_post();
$attachment_id = get_field('header_bg_image');
$size = "wide-thumbnail"; // (thumbnail, medium, large, full or custom size)
$image = wp_get_attachment_image_src( $attachment_id, $size );
if ( ! empty( $image ) ) {
$image_html = esc_url( $image[0] );
} else {
$image_html = 'https://rasons.ltd/wp-content/uploads/2020/02/interior-exterior-finish-800x400.jpg';
}
printf( '%s', get_the_permalink(), esc_attr( the_title_attribute( 'echo=0' ) ), get_the_title() );
}
echo '</ul>';
wp_reset_query();
echo '</div></div>';
} // end foreach.
echo '</div>';
?>
