Could possibly use a plugin to create a pvp zone that will enable that flag in an area Like Pelayori's safe zone plugin.

I am hoping that the map maker can fix the ruins so they are destructible on PVE. It sounds like that would bring so much fun to a PVE map.

have you tried to enable friendly fire at the ini?
In Game.ini you have to ensure the following:
[/script/shootergame.shootergamemode]
bPvEDisableFriendlyFire=false

This option is enabled on my test server and that did not allow for it. I have yet to try the plugin option test to see if that works since it enables player damage in the area of effect. Not sure about structures being affected.
