Apple does not provide a dedicated switch or setting inside macOS or the Preview app to permanently disable or turn off the form-filling AutoFill feature (which Apple calls "enhanced autofill).
Because Preview pulls this data directly from your system and the Apple Contacts app, the only real workaround is to use an alternative PDF editor. You can switch to third-party PDF tools like Adobe Acrobat Reader or PDF Expert, which let you explicitly toggle form autofill features on or off
More info on form filling and Preview from Apple:

If you want to use a different app for opening a PDF on your Mac, you can change the app for that one file or for all PDFs. Select a PDF file in Finder then select File menu > Get Info, and in the Opens With section, set it to something else.
If you want to make that other app the default for opening all PDFs on your Mac, after selecting the new app click the Change All button then confirm.
