How to configure Vault with an external CA to use ACME protocol?


We have vault version v1.14.2 installed behind a loadBalancer (several nodes form a cluster)
Our CA (certificate authority) is AD based. Can we used Vault and configured it to used the ACME protocol to create certificates against an external CA?
We want to use the pki with certificates generated by our CA.

How can we achieve this ?

Best regards,
