Disable payments for products

Hello;

I want to disable some payment method for a few products.

I have code that works well:

add_filter( 'woocommerce_available_payment_gateways', 'filter_gateways', 1);
function filter_gateways( $gateways ){
    // Not in backend (admin)
    if( is_admin() ) 
        return $gateways;

    // Storing special product IDs in an array
    $non_pp_products = array( 6009, 6010,6011,6012,6013,6014,6015,6016,6017 );
	
    // Needed variables
    $is_non_prod = false;
    $is_prod = false;
    $count = 0;

    foreach ( WC()->cart->get_cart() as $cart_item ) {
        // count number of items if needed (optional) 
        $count++;
        $product = $cart_item['data'];
        if( ! empty($product) ){
            $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;
            if ( in_array( $product_id, $non_pp_products ) && ! $is_non_prod ) 
                $is_non_prod = true;

            if ( !in_array( $product_id, $non_pp_products ) && !$is_prod )
                $is_prod = true;

        }
    }
    if ( $is_non_prod && ! $is_prod ) // only special products 
    {
        // unset only paypal;
        unset( 	$gateways['bacs'],
        			$gateways['przelewy24'] );
    } 
    elseif ( $is_non_prod && $is_prod ) // special and normal products mixed
    {
        // unset ALL GATEWAYS
        unset( 	$gateways['bacs'],
        		$gateways['przelewy24'] );
    }
    elseif ( ! $is_non_prod && $is_prod ) // only normal products (optional)
    {
        // (unset something if needed)
            unset( $gateways['cod'] );
    }
	return $gateways;
		}

Unfortunatelly, I have to put every variation’s id into the code.

It would be much easier to put only main product id and automatically get all of its variationas.

I know there is a function ->get_children(), but i dont know how to use it in practice.

I would be grateful for any advice.
