Hello ​@c.ananiasdelaguila 
Thank you for reaching out, and welcome to the Docusign Community! We appreciate your question and assure you that we are fully committed to providing you with the best service possible.
Unfortunately, we can only enable that feature in a developer account for testing, not in a Free Trial. I highly recommend that you create a developer account and submit a request to enable the feature via a support case.

Hello.

Thanks ​@Ma.Cubio . I really appreciate your answer.

I'm speaking with a Spanish DocuSign sales representative to discuss this issue.

Thanks ​@Hengfeng Ge . I find your answer quite helpful. In fact FNMT’s certificates fortunately are supported by DocuSign.

Best regards,

Carlos.
