Remove Customer Information In Vendor Orders Page

How can I remove the customer information, shipping address and billing address block in vendor panel in the orders page.?

I tried following this https://forum.cs-cart.com/topic/52462-hide-in-order-customer-informaion-vendor-panel/

and this https://forum.cs-cart.com/topic/58822-remove-customer-information-from-vendor-order-page/

But it doesn't work.
