Encrypt the form with the PKI key

I have a form that I created but I do not see the option to encrypt the form with the PKI key. Can you assist me in getting this set up for my form.

Good day, forms can be encrypted as shown on this guide: https://www.jotform.com/help/344-encrypted-forms-and-how-to-use-them

However, I am not sure if it can be done via JotForm API, please contact our API team: api@jotform.com
