Back in 2005, PaleoJudaica noted claims that the Vatican owned two small Dead Sea Scrolls fragments. See here, here, and here. And note the linked-to post at the old Megillot list by Stephen Goranson. These appear to be the same fragments. Goranson has additional comments at Nongbri's 2021 post, linked to above.
I agree that the one in paleo-Hebrew script is unlikely to be from the Book of Daniel, even though it shares a word with Daniel 11:36. I would be very surprised to see a copy of Daniel in paleo-Hebrew. Also, although there is little to go on, the beginning of the next line does not look like anything in the immediate context of that verse in Daniel.
