add_filter( 'woocommerce_get_availability_text', 'wiseowl_custom_get_availability_text', 99, 2 );
  
function wiseowl_custom_get_availability_text( $availability, $product ) {
  $stock = $product->get_stock_quantity();
  if ( $product->is_in_stock() && $product->managing_stock() ) $availability = __( 'Quantity: ' . $stock, 'woocommerce' );
  return $availability;
}

this is for fucntions.php  or simply remove sock control in metadata in product input page.
