Configure nut as a net client via luci on x86

As it says in the topic. I can see how to configure a local or net server for nut but I'm trying to configure nut on an x86 openwrt router as a net client. My ups is monitored by a separate server that also provides the net server functionality.
My topology may change in the future but for the moment it is what it is.
I've done this setup previously on linux machines but can't seem to find where you can configure the nut client into netclient mode via uci or luci.

See Where is luci-app-nut supposed to be?
You may need to manually edit /etc/config/nut_monitor for the first time to enable it.
