Unfortunately i can't guarantee compatibility with external mods.

As for your question, yes you can remove learned skills by directly editing the mod file.
Simply comment out the number of the skill you don't want in sections where the name appears, for most skills it should be as simple as commenting it in the FNH1_SKILLS or FNH2_SKILLS depending on Fear & Hunger game you are playing.
As what i meant by "commenting" is adding "//" on the line where the name of the skill is present, example:
Let's say you want to don't want to learn hurting in Fear & Hunger 2: Termina, in order to do so you have to comment out the line in which the name of the skill is present:
const FNH2_SKILLS = [

// 12,  // hurting

If you want to revert this change simply remove the "//" in front of the number like so:
const FNH2_SKILLS = [

12,  // hurting

If you want to completely make the game think you haven't learned the hurting skill then you'll have to also edit the other sections where the skill's name is present such as:
- FNH2_SWITCHES
- FNH2_VARIABLES

But i feel like simply removing it from the skill list like the example i've shown before should do the trick 90% of the time.
