privacy – What settings required to privately run bitcoin core on tails?

I am running bitcoin-core on TailsOS which seems to work out of the box. I think TailsOS blocks all unsafe requests but I would like to know what settings I should enable to run it really privately. So far I start my node via

$ ./bitcoin-qt onlynet=onion

Is anything else required? In this answer I read about a bunch of other settings but feel that isn’t required on tails, correct?
