No. Its all text file config. You wouldn't use live CD mode. You define your own how you want it to work.
Its a steep learning curve so if looking for off the shelf solutions, don't use nix. If you need something custom but through a single config paradigm, nix is awesome.
Less public / archived spaces as well. Videogame lobbies were rampant with Trump / MAGA messaging in 2019. Not sure what its like now as I quit all online gaming. Anyone 14-17 during that period who are now of voting age has likely gotten a massive dose of right wing propaganda.
