That's what I guesseed too (as this property could be found into the src code).
But... I am still a bit surprised it's not, at least, mentionned into the doc (into some dedicated section).

Yes something like that I guess. You can add the disk_access_mode property to your cassandra.yaml and set it to standard to disable memory mapped access, it will work. It's the same thing for the auto_bootstrap parameter and some other property like these two, they are not written in the conf anymore but still read if they exist.
