Complete beginner

I could really use some help with a couple datapacks.  


    

  1. I have a mod in my modpack called Scaling Health (1.20.1 forge). and I have a few ways in the modpack to get permanent hearts.  I'm wanting to limit it to only be able to add 10 hearts from the Scaling Health Mod.  Looking at their discord it appears they have some examples, but I'm completely lost.
    2. 

  2. Adjust the loot drops.  Currently, the heart crystal from Scaling Health drop way too much from mobs.  I'd actually like to remove that drop from mob drops, and only allow for the heart crystal shards to drop.  This would keep the recipe for the heart crystal, but not let it drop from mobs.  This would be to just make the modpack a little more difficult and slow down progression.
