I've never posted on a forum before, and this looked like the right place to put this question.
Is disabling Peaceful mode on an already created (and heavily played) save possible? If so, how would I accomplish doing so?

I'm sure you could do this with a console command, or you could use this mod https://mods.factorio.com/mod/ChangeMapSettings .

Hello, you need to use cheat command.

Start by turn off the peacefull mode then you need to kill all biter to reset them.
