Force download PDF from AWS S3 Presigned URL

I have access (paid for) to a pdf hosted on Amazon Web S3. Access was granted via a pre-signed url. The pdf opens in browser but I want to download it.

After reading around, it seems that this was due to the content-disposition header settings (server-side).

What can I do with the url, client side, to override the header or otherwise force the pdf to download?

There is not anything that you can do, because of the way signed URLs work -- they are intrinsically tamper-resistant and essentially completely tamper-proof for all practical purposes.

Changing anything about a signed URL after it is signed invalidates the signature.

Disallowed changes include adding/removing/modifying the response-content-disposition query string parameter (which allows the Content-Disposition response header to be modified/overridden for that request).
