RTF is a global modification that replaces all towns in the game.

EVA contains many NCF creatures from the megapak, and I don't know anything else about it, but the skill wheel can be changed.

It's likely that the same files are affected.

Here's my version of the mod where only the skill wheel and the starting skills of the heroes are changed; I've updated all the files.

Should I unpack it into the mods folder or the data folder?

I'm not saying the mod is bad; many things are very good, the elementals and water creatures are particularly well done. I haven't tested the dark dwarves, but the manticores already seem appealing, and for the undead, please make the third-tier units wolf skeletons; this works well in one of the mods, and replace the undead with dark knights. I'm still looking forward to it; when is the release planned?
