Openvpn management interface not supported?

Installing and Using OpenWrt Network and Wireless Configuration

LuCI can add management field into openvpn config but openvpn build itself doesn't seem to support it

Options error: Unrecognized option or missing or extra parameter(s) in openvpn-server0.conf:12: management (2.4.4)
Use --help for more information.

Tested same config on Ubuntu and it works.

How would you stop and restart the VPN server remotely to apply the configuration..unless you were connected to the LEDE using another method?

This is my test environment x86 box so I connected to LEDE using another method - not excluding keyboard and display.
If configuration is okay you can just run

/etc/init.d/openvpn restart

It will recreate openvpn configs and restart it. I'm considering this a dangerous way if vpn tunnel is the only management channel.
