you can't delete it in upload/download? I've never really tried doing that, but if that doesn't work, maybe try going into the update folder manually through ftp and deleting what you find. you can apparently block updates in there, but it will undo itself after a shut off or a kp. in fact, my power went out about thirty minutes to an hour ago, so I have to redo the exploit on my ps4, and I lost about 10 minutes in berseria on the ps5. not too big a deal, but I also don't care if my ps5 updates, just so long as it doesn't while in rest mode.
