Hide the SAME_AS_BILLING checkbox BUT keep shipping options?

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.5
-- PHP version -- : 5.6.29
-- Browser(s) name and version -- : Chrome 55.0.2883.87
-- Error-message(debug-mod must be tuned on) -- : no error

I have a query about Hikashop addresses. The website has to display products for customers to select, which creates a quotation rather than an order, as no payment is involved and shipping costs are agreed by phone. The website has to collect a shipping address and a choice of 2 shipping methods, but no billing address. I've set this up by using language overrides to swap the names of Shipping and Billing addresses, but now I am asked to remove the tick box for SAME_AS_BILLING.
Is it possible to hide the SAME_AS_BILLING checkbox, but still keep the choice of shipping methods. Also is it possible to hide the second address in the customer emails?

Thank you, the CSS works fine to hide the SAME_AS_BILLING checkbox.

But I still have both addresses printing on the confirmation emails - how can I stop the second address from printing?

Managed to work this out myself, I removed the <!--{IF:SHIPPING}--> lines from the html part of the emails

Thanks for your help with the checkbox.
