It seems, that some screen readers are somehow overriding the "Content Accessibility Enabled" attribute of pdf documents so the document is displayed as normal PDF document. Currently I have one document which I can not read with NVDA but I can open and read it with JAWS. After analysis of my friend it seems, that JAWS just override or ignore the mentioned attribute. As I am not owner of the document, I don't attach it here, but I can send it privately.
I am not sure about legal or technical aspects of this issue, but from the user's perspective this should be a partially good solution for protected pdf documents.

Not sure if this helps but now I opened the document in QRead which is a commercial software for reading e-books from q-continuum, developed specially for blind people.

For Adobe Reader, this requires a special key from Adobe. Unfortunately, we can't include such a key because NVDA is open source and it would therefore be much easier for someone to extract the key, which would violate the agreement with Adobe. Because NVDA's plugin framework is unrestricted, it would also be possible for an add-on to do things which the document's author has disallowed such as copying text, which would again be in violation of the agreement.

Leaving open because ideally, we might be able to find some way around these problems.
Changes:
Changed title from "override the "Content Accessibility Enabled" attribute and display pdf document as not protected" to "Adobe Reader: Support protected PDF documents"

@jcsteh You expressed a few thoughts and concerns about this ticket in #3350 (comment) almost four years ago. Might you have any updates with regards to the request given that Adobe Reader has changed significantly and is now Adobe DC/Acrobat Reader?

There have been no changes in Reader related to this.

It is still an issue, but it depends how strong the protection is. You can protect your pdf document in several ways. If the protection is not sstrong, then NVDA recognizies the text. I think @derekriemer wanted to start some research on this.

I think without a sample document we will not be able to investigate further. I am adding the blocked needs info label. If anyone has a protected pdf where this issue occurs, please attach it here.
