How to disable Massive Pirate Invasion Mega Event

Hi,

So on my 2nd game, things where going really well until an event spawned tons of high-tech pirate fleets around the map. Despite being in a really strong position compared to other nations, my fleet was crushed even against a smaller subset of a random pirate fleet.

I know they won't invade or replenish ships, so that I can still win in the long run or just simply go for tech win, but it seems cheesy and really boring, so I'm just going to restart!

I don't necessarily want to disable mega-events, but I don't really want to  come across this event ever again. They basically had laser weapons while the rest of us where running around with crossbows.

TLDR; Is there some config file or list where I can edit out this particular event?
