Hi,
There isn't an automatic way to do that, but it might be possible to remove it with code. If you can send the PDF in questions to us we will look into it and see what we can find. You can use our contact us page to send the files to us:

If you are beyond one year, then you may need to renew your maintenance subscription or purchasing a new license in order to be eligible for support.
Thanks!
