Hi @priscillacouto,
Welcome to the Docusign Community!
We are glad to have you here and can't wait to help share as much knowledge as possible. I am sorry to hear that you haven’t been able to update your Web Form’s field validation settings, but I will assist you in solving the issue. If the field in question is linked to an eSignature field, try updating the field’s validation in your template, and then generate a new Web Form based on it. You can find detailed steps on how to edit your template, here:
To edit a template
