How to Set Up a Non-Typable Signature Field in Adobe Acrobat Pro

I'm creating a standard application form in Adobe Acrobat Pro that will be filled out by a staff member and signed by an applicant on the same laptop. I need to create a Digital Signature Field that only accepts a true signature, drawing or using a digital signature "pad". The signature field should not allow typed text; it must enforce an actual signature. I tried all the different options in adobe; but I either end up being able to just type text in the signature box; or have to create an entire digital ID; or have to use request e-signatures via email; which i don't want.

Goal:

I need a signature field that requires a proper signature (drawn) without allowing any typed text. Ideally, I want to save this form as a reusable template on my laptop so that I can open it, fill it out with each new applicant, and have them sign directly on the same device.

Question:

How can I set up a non-typable Digital Signature Field in Adobe Acrobat Pro that enforces a real signature and does not allow typing? Any help would be greatly appreciated!
