The Verdict: Not eligible
Reacquisition only restores nationality someone had, so this route is closed to you. If a parent or earlier ancestor was Brazilian, take the citizenship by descent quiz; otherwise look at naturalisation.
Brazil has no generational limit on descent, and recognition counts back to your birth.
Without Brazilian ancestry, citizenship comes through residence and naturalisation: four years in the ordinary case, one year with a Brazilian spouse, partner or child, or a Portuguese-speaking nationality. Residence routes include remote work, a pension, investment, a job offer and, for most South American nationals, a residence agreement.
