[ECP-8798] Alternative methods configuration and V9

[Nuranto]

It seems we cannot change payment method name from Magento's backend.

For example, we want to display "Pay in 3 installments with Alma", instead of just "Alma", and it seems there's no way to do it.

Is there a way, or is this just a missing feature ?

We did not find either a way to enable/disable a payment method from Magento. We can do it via Adyen's backend though, so it's good enough for us. But I guess in some cases, this would be usefull too. (for instance if we have a mobile app channel and want a payment active on app mobile but not on Magento)
