Drupal commerce display VAT exclusive unit price & subtotal for line item in cart and order
Finally I find this module: Commerce price by components

This is perfect for my requirement.


  Extension to Drupal commerce that provides a price formatter to enable/disable price components such as discounts or taxes when
  displaying prices. This gives the admin absolute control over which
  components should be displayed and which shouldn't. It also provides
  two Views handlers to display/hide price components in cart totals and
  order totals. Additionally it has basic rules support that gives to
  the commerce administrators the ability to do conditions using price
  components such as discounts or taxes and react accordingly.
  
  Example use case
  
  If you want to customize your cart or checkout views, you may want to
  display prices with taxes and without discounts (or viceversa) in your
  line items but the total amount should be displayed. Then you enable
  this module and choose at formatter level (both display fields and
  views) which components you want to hide or display.
