I added a few new environment variables to the below file and I want to restart the service.  I don't want to reboot the Operating system/Virtual machine for the new environment variables to be effective.

Note: Starting from version 2018.1, the file "tabsvc_0.service" is located at:

/var/opt/tableau/tableau_server/.local/share/systemd/user/tabsvc_0.service

This command does not work,  I have tried this already.

sudo systemctl restart tabsvc_0.service

Also this "tabsvc_0.service" does not show up when I run  sudo systemctl or  systemctl list-unit-files.
