I am trying to make it so building blocks cannot be removed at all and entities can still be removed.. any thoughts?

found it under, changing all grades to false

 "Remove Info (Refund & Price)": {
    "Price Enabled": true,
    "Refund Enabled": true,
    "Refund Items In Entity Slot": true,
    "Allowed Building Grade": {
      "Twigs": true,  //Allow removal of Twigs
      "Wood": true,
      "Stone": true,
      "Metal": true,
      "TopTier": true​
