Question: Deny a specific Block/Item, but allow others?

Hello,
If i set `itemRestrictions` to **false** and don't give the player a special permission, they will be able to interact/blace/hold, etc. with any item or block, right?

But if I give a player for example the permission:
`-modifyworld.blocks.place.3`
Then they can't place dirt anymore but any other block, can they?

Hope you can help me.

Best wishes,
