If it's only for not so tech-saavy users, you can disable download in the chrome pdf viewer by generating one-time usable unique urls eg.

It is probably also less performant than the chrome pdf viewer.
If you turn the content into images, users can still take the batch of images and combine them into a pdf, however in this case the text is harder to recover, but still possible with OCR. If you want to make it harder to copy the content or just detect it, you could also use watermarks in your downloaded images or incorporate steganography to identify the user who made the copy based on the released file found in the wild.
Be aware that watermarks can always be removed, usually very easily from PDF files and it is a bit harder but still possible to remove from images. Carefully designed hidden identifiers steganography can also be removed but it has to be found first and usually users don't look when a document is not obviously stamped.

Hi, I don't need to actually prevent downloading the file, as that is not possible since like you said it is in the temp file system. I just want to hide the toolbar in the chrome PDF viewer to satisfy an arbitrary client request. If I inspect the element using developer tools and then add display: none it does the trick, but I'm not sure how to set that by default.
