I remember seeing that setting in ETACS as well, but I never tried to change it. Have you noticed any difference in the different settings? (I mean, does it actually change anything?)
It'd be really cool if I could completely turn off EPS, I don't need it at low speeds and I can +1 your feeling about it at high speeds -- Feels like it's over-correcting too much when I'm barely touching the wheel.
