Delete EA items from CAS?

I have never made a post here before. Sorry if I do something wrong.

There are some clothing, hair, etc. items in CAS that I have never used, and I know I will never use them. I simply do not find them aesthetically appealing. This was fine back in 2014, but now with all the various add-ons, the list of items is now incredibly long and it is difficult to sift through them all to find what I'm actually looking for. I had hoped I would be able to go into the game files ( C:\Program Files (x86)\Origin Games\The Sims 4\Data ) and simply delete the files of the items I don't want, like I would in the mods folder for CC items. But either this is not how that works, or I didn't look through enough folders.

My questions are:

1. If the method I tried is possible, what is the path for the folder I need?

2. If I do this, will it be gamebreaking? I am fine with some visual glitches but I don't want to do serious damage.

3. If I am totally on the wrong path, what method could I try next? Is there a mod I can use?

I tried searching for these answers on my own, but I think I might be the only person looking for less options haha
