How to expose one drive to Jellyfin

[confusedcatgirl]

Well, I am now asking this question because I haven't found any proper solution for my specific case.
How do I block Jellyfin from exposing certain Drives on Windows 10?

Here's the thing. I have multiple drives in the computer hosting Jellyfin.

The following drives are in my system:
C:, my Windows Drive, NTFS
D:, my CD-ROM Drive
E:, my external Data Storage, exFAT
Z:, a drive specifically for server hosting, NTFS.

Jellyfin runs through windows directly, running on Z: via the installer.

I want to specifically ONLY expose Z: to Jellyfin, and only a specific set of folders too.
It sounds strange, but I want to only expose this set of folders to the server, the rest should be hidden.
I already attempted to create a Jellyfin user and set safety through security, however, that did not work out.
The reason is, that exFAT does not support Security, thus exposing plenty of data.

How do I resolve this issue?

I don't think this will be possible without making all the other drives be hidden for you too.

I will say, this exact thing you want to accomplish is very easy to do with Docker.
With a Docker container, you can literally mount as many drives/directories to the container as you want/need.
So the Jellyfin server inside the container will only have access to that one drive/directory if that's the only one you mount.

If you ran Jellyfin as a service you might be able to. Create a new user, install jellyfin as a service, configure the service to run as this newly created user, set drive permissions accordingly. Your user is still able to see everything, the new user only sees what it needs to run Jellyfin.

Well the problem I see with docker is: It's not very "useful" for my situation. I want it to run productively for myself, so I can access my media from all my devices. I had no bad experiences with docker, but no good either.
I will take the service suggestion into account and look into it.
