what's the restriction atm? I am not aware of any, depending on your status tho. See this FAQ on the HiveFest Support site about Covid Restrictions, especially the second paragraph on EU entry from non Schengen zone (like brazil) https://hivefest.freshdesk.com/support/solutions/articles/80001029295-covid-qr-health-pass-vaxx-mask-in-netherlands-tl-dr-no-requirements-
Great to know that Europe is getting back to normal. Had I known I'd have prepared myself earlier. No way I'd travel up there like crazy again hahahahha customs in Frankfurt almost denied my entry in 2018 because I had no money on me, no hotel reservation, no proof of event, nothing 😂
