How can I setup LACP in XCPNG without using XO?

Is there a way to achieve this? I am handing out addresses via DHCP static mapped to MAC address and I have LACP already setup on my switch. I am trying to figure out how I can get the initial LACP setup in XCPNG without having to undo the LACP configuration in my switch

I have not tested, but this should work:
LACP Bonding in XenServer - Configuration and Troubleshooting.

I’d put a temporary connection on another port and install XOA demo or XO from sources, then set up the primary LACP ports.

Have you checked to see if XO Lite has this function? They add new stuff very often but I haven’t been using it: XO Lite - Server Virtualization Administration Made Simple
