I can't find a mod that allows setting the current evolution factor nor the 3 influence values (pollution, damage, time). But this seems to fit best with ur mod, so I'll leave this here ...

never did modding factorio or lua but this seems to work for setting evolution back to 0:
"for k,v in pairs(game.forces) do v.evolution_factor = 0 end"

so maybe u can utilize that?

and for the 3 influence values:
"game.map_settings.enemy_evolution.<name> = <number>"
time_factor
pollution_factor
destroy_factor

So, is this possible to implement and is there a chance of this coming soon? :)

Right now I am in the process of re-doing the settings gui. I will keep this in mind at a later point.
