what assists are allowed in Leaderboard challenge?

The challenge in talking about is Group 5, various tracks. My difficulty is Get Real. I okay with manual clutch and h-shifter no assists. Can you do the challenges and still be Get Real difficulty if you use autoclutch and paddle shifters?

I not able to find anything in searching for this info. I basically want to know if I'm competing on the same level as others. In AMS2 it actually tells you what the others are using IIRC
