How to exclude for specific categories

You can achieve your requirement by adding the below code in your child theme’s functions.php.

add_filter('thwwc_show_wishlist_button', 'th_hide_for_specific_cat', 10, 2);
function th_hide_for_specific_cat($show, $product){
    $terms = get_the_terms( $product->ID, 'product_cat' );
    $cat_present = false;
    if($terms){
        foreach ($terms as $term) {
            $product_cat_name = $term->name;
            if($product_cat_name == 'Category Name 1' || $product_cat_name == 'Category Name 2'){
                $show = false;
            }
        }
    }
    return $show;
}

Hope this helps.

Thank you!
