Customizing Cybersource payment form

Hi Experts,

We are using Hybris 1808 & currently using Cybersource HOP payment integration and wish to customize the payment form using SOP but I don't see any documentation on SOP implementation but instead it re-directs me to Cybersource Secure Acceptance Hosted Checkout API. Is there any way I can use SOP to customize my payment form or if Cybersource Secure Hosted Checkout API is the only solution for customizing my payment form then what changes I should be looking into for moving from HOP to Secure Acceptance.

Thanks in Advance
