How can I prevent document level script from running again after it is securely signed?

New Here ,

I have a PDF template which accepts a secure signature from a signing pad, and which also has doc level scripting that inserts the current Date into a form field, and Policy Number into the next form field which is taken from the PDF file name. As the date and signature go hand in hand legally, I need to prevent the form from updating the date the next time the signed form is opened. Currently, the date changes on me on re-open. How can I prevent that so the form remains static after signing?
