Disabling autofill for non-interactive PDFs

My IOS app generates pdf files.

Every time my users open the generated pdf files, the autofill popup jumps out, but my pdf file is NOT for interacting.

I'm here to ask if there's a way to mark my pdf files as "not a form", like in metadata or anywhere else?
