Trying to stop HA in order to get the zwcfg...xml file to udpate

I have a stale zwave xml file in config, or the file is for zwave 1.4 not openZWave. I read this thread that says to quit HA, but I am not sure how to do that.
Is quit the same as ‘server-controls>stop’?
I have OpenSSH add-on installed, but there is no stop command. Or this is for the old zwave integration and does not apply.
For OZW running on an RPi with Hass.io, is there a way to get the ozwcfg…xml file updated to show the nodes?

Yes. Or this command via ssh:

ha core stop

And this one when you’re done updating the file:

ha core start
