Hide payment method on checkout

I want to hide the payment method BAC on checkout.
I still want to use it on the backend for known customers, so that i can send invoices for manauly added orders on the shop back-end.

How can i hide the option payment_method_bacs on the shop checkout page

i tried to figure it out but cant find the right code.
This is what i came up with:
#top .woocomerce-checkout-payment
.wc_payment_methods payment_methods .methods
.wc_payment_method .payment_method_bac {display: none !important;}

Thanxs for the support
