paynow button / feature and the paybutton removal

-- HikaShop version -- : essetials
-- Joomla version -- : 3.2

Question:
In the order screen where a customer can :
lookinto his order list and re-order or pay now .

We would like to remove the pay now button /feature and the payment methods dropdown
Could you explain how to do this correctly?
Because don't much about PHP

Hello,
The solution will probably be to set the "Payment of orders not paid immediately" option to NO, through "Hikashop->System->Configuration->Main".
