Can't use mods on SW BF 2

Hi, I recently got Starwars BattleFront 2 on the Epic Games store for free and linked it to my Starwars Battlefront 2 from Origin that I bought during the release in 2017 to get the celebration edition's features.

I used to play a lot with mods and now I can't because of the Epic Game version, every time I launch the game from Origin the Epic Game Store is starting aswell and it prevents me from playing with mods. If I delete the Epic Game Store the game will simply not launch.

I would want to know if there's an option to disable the launch of Epic Games when playing on Origin, or just a way to fix this please.

(Sorry if I made any mistakes, my english isn't perfect)
