How to make plains generate more than grassland?

[Shado_w_]

I'm new to modding and this looks like it involves lua, so Im kinda lost.

If it helps, here's path to a file where plains and grassland mix seems to happen: D:\SteamLibrary\steamapps\common\Sid Meier's Civilization VI\Base\Assets\Maps\Utility\TerrainGenerator.lua

You don't need mods.

Play Apocalypse (mode)

Thanks for suggestion, but I don't want to play Apocalypse, it seems too extreme for me.
