PDF scanning is done by both OCR and PDF analysis so no. If you, a human can read it, a bot can read it too.
Your best bet is the classic inserting BS in a 1-hex-off-white font
This is correct. There are also typefaces that are designed to be difficult for OCR eg https://www.librarystack.org/zxx/
These are, however, difficult for humans to read as well.
