I'm going to tell you what it is about. or I'm going to tell you what is it about.
Neither are direct questions, nor indirect because they don't have the typical starting phrases (could/can you tell me, do you know, would you mind telling me...), or is it? Which one would be correct and does that function have a specific name or grammar rule?

I have no trouble calling that an indirect question. For that reason, use "... tell you what it is about".
