UI Dispplay HUD Size/Scaling

hello! im playing on a 3840x1600 21:9 Ultrawide Monitor.

and the current ingame settings only allow me to scale my HUD to 80% which is still way to big for such a resolution.

Does anybody know a workaround?

Ive tried to edit the

<path-to-game>\EFGame\Config\

But i cant find a proper line which could effect it in any way :/

thanks!
