Could you please tell me how to make an artifact buried in the ground when creating maps?

1. Only the Grail can be buried – in the editor, it is the last in the list of artifacts. 2. Never heard of that. Isn't your native editor enough for you? 3. Apparently not. Such scripts only exist in WoG. There are many other things there :) 4. Probably, it is possible – extract it from the resources, modify it, and put it back...
