If you cannot appeal (and you probably can't, since this was a judicial order by the Supreme Court), then you have to comply (or face the consequences of ignoring judicial orders).
If the argument is that it is illegal to "censor", due to the Brazilian constitution, then Twitter is already engaging in illegal behaviour whenever it bans accounts (or auto-removes tweets) for using terms Musk dislikes (like "cis" or "cisgender").
I really don't buy the "free speech" argument here, since Twitter has never been an "absolute free speech" space to begin with. Note that Musk had no problem censoring and banning accounts when asked by the Turkish or Indian governments.
