remove price for "related products"

Hello, I have a specific category who I don’t want to sell the products, but I need to show it anyway.
So I added a code in function.php and works (don’t show price filtered by “slug”) but if I enter in product page there (on page footer) I can see the prices (for same category) (see capture) on “related products”.

it’s possible to hide that too?

this the code to hide by “slug” (in this case slug=”capsulas”)

// Specific product category archive pages
add_action( 'woocommerce_after_shop_loop_item_title', 'hide_loop_product_prices', 1 );
function hide_loop_product_prices(){
    global $product;
    if( is_product_category('capsulas') ):
    // Hide prices
    remove_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10 );
    // Hide add-to-cart button
    remove_action('woocommerce_after_shop_loop_item','woocommerce_template_loop_add_to_cart', 30 );
    endif;
}
// Single product pages
add_action( 'woocommerce_single_product_summary', 'hide_single_product_prices', 1 );
function hide_single_product_prices(){
    global $product;
    if( has_term( 'capsulas', 'product_cat', $product->get_id() ) ):
    // Hide prices
    remove_action('woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );
    // Hide add-to-cart button, quantity buttons (and attributes dorpdowns for variable products)
    if( ! $product->is_type('variable') ){
        remove_action('woocommerce_single_product_summary','woocommerce_template_single_add_to_cart', 30 );
    } else {
        remove_action( 'woocommerce_single_variation', 'woocommerce_single_variation_add_to_cart_button', 20 );
    }
    endif;
}

I don’t sure if this exactly are cover by customer support but, it’s no problem if not.
Thanks so much anyway!
