Yes, that is the way to do it.  You do need to reboot afterwards for
that command to take effect.  I have never tried this, but it should
shut down the debug shell immediately if you do this:

sudo systemctl stop debug-shell.service

which would avoid the need for a reboot.  Test to make sure it worked
by doing Ctrl-Alt-F9.  There should no longer be any response from the
shell that was running there.  You would still need to do the
systemctl disable command or the debug shell would be back at the next
reboot.

If you have never used things like Ctrl-Alt-F9 before, you need to
remember that Ctrl-Alt-F7 will get you back to the GUI screen.  During
shut down, the GUI goes away fairly early, so when trying to debug
shutdown problems, if Ctrl-Alt-F7 does not work, that is not a problem
as all it means is the GUI got shut down normally.  Just do
Ctrl-Alt-F9 to get back to the debug shell again.
