I am making a nod pack and have disabled all of the hammers and claymores from Paladins however they still show up in the villager trades. It would be nice to be able to toggle the different weapons from being traded.

Sorry this is just way to much work, this won't be implemented for 1.20.1
As far as I know, in MC 1.20.2 these are data driven, hence it will be possible in the future.
