Negative

They claimed it was replaced with steel because of emissions or some crap.

2017+ F80 New BMW M3 and M4s will be fitted with steel driveshafts instead of carbon fiber ones as a result of the German manufacturer complying with emissions regulations, according to Autoblog. Apparently, the old carbon shafts were too thick to accommodate a new particulate filter on the exhaust system.
Actually some of us received replacement driveshafts constructed of CF.
New production;

I think 2015 had a steel shaft; 2016 had carbon fiber,
Then 2017+ was steel.

If you had a malfunctioning 2016 and it had carbon fiber I think they would replace with carbon fiber.

That said; unless CF was out of stock and no fitment issues with a steel then some circumstance I could see a steel or CF shaft as an option.

What year is your F80?
I am on my second F82. The first was a 2015 YMB. My current is a 2017 Nardo Gray (...purchased Oct'2016).
