you'll want to extract the tables you want with fmodel, (look in xrd777\battle\tables), download 010 editor and these templates for it to make hex editing easier, then just open up DatEnemyDataAsset.uasset, etc. in 010 editor, run the corresponding template, and it should be pretty easy from there. search 010 editor or table editing in the discord search, and there's some other tutorials on it floating around.

the skills listed in DatEnemyDataAsset are just for passive skills and ones that appear on the analyze screen, not attacks. editing enemy movesets requires editing the flowscript for an enemy's entire ai. you'll want to extract BF_BtlAi0[IDnum].uasset with either atlus script tools or unreal atlus script, then you can edit the ai script in notepad or something.
