Where in the file system does the UDMP-SE store it's ipsec tunnel configuration?

UDMP is running UniFi OS 3.1.16 and I need a specific VPN configuration that StrongSwan supports but isn’t possible to do in the GUI. Three years ago the files I need were located in /run/strongswan/ipsec.d/tunnels/ but they are no longer there. Does anyone know where they live now -or- how to edit a VPN config outside of the GUI?
