Are heavy mods still heavy when you disable 90% of their features?

I am using the lycanitesmobs mod, which is by far the heavyest mod that I use and I want to take some stress from my cpu, but I disabled like 90% of the creatures from the mod (because some of them are ugly as sh*t)

Is the mod still heavy even though I don't use everything or becomes the mod way less heavy?

Disabling individual parts of the mod won't change its impact on your performance as the entire mod will still be loaded into the game.

Thanks, I wasn't sure if it worked that way
