Can I perform administrative functions via ssh?

Hi all,
Can I perform administrative functions like adding users and setting permissions as well as creating shares and configuring them via ssh? I ask because I am blind and the interface of the ex2 ultra is bad in terms of screen reader accessibility. A classic case in point is the dialogue to add a user. I can go to the users tab but the actual icon to add a user is not visible to the screen reader. This is a user interface design issue about which I can at the user end do nothing.

I hope wd is listening and why I would prefer to administer this box via ssh.

Once you have ssh connections established you can do any admin task you like. I have EX2 Ultra and a Single Bay Gen2. For example I setup cron to rsync data between devices daily. It’s much easier as never need to change it compared to the nonsense of dealing with backup software which I have no idea if it will even work restoring. So I also always have a recent back up and without any bloated backup software in some odd format that may go obsolete.
