Newbie in need of help for backup

[TheDreadPirate]

In the comment above the one I linked, it mentioned the need to install Nvidia drivers from QNAPs app store. Not sure if you've done that part yet. And the steps in the solution seemed reliant on that happening first.

But, honestly, this may be better to ask on QNAPs forum. This isn't a Jellyfin specific question at its core. It's a "how do I pass my Nvidia GPU into a container on QNAP" question. There are not a lot of QNAP users, and even fewer experts, on this forum.
