Is it possible to work without shopping cart?

Hi everybody,
I need to implement very simple use case. The user should be enabled to buy only one product at a time. So after choosing it from the catalog s(h)e should be able to go with one click directly to checkout. The phase of putting product into the cart is not necessary and the cart should not be even visible on the front end.

Is that customization possible in HikaShop;?

Thanks.
Jack
