One that I'm familiar with is the BFII modding Discord.
I suggest you search for modding communities and ask this there. No mod is 100% safe, and EA/DICE updates their bots from time to time so mods that used to work just fine may start getting people banned 'out of nowhere'. However you can mod the game if you're playing offline, and if you do it online you may never get penalised if it doesn't trigger their bots.
