Hello, I have the same issue, and cannot access the support link.
I get 403 Forbidden nginx and I'm from Brazil aswell.
I would like to check and download newest drivers for Windows 11 and BIOS, if any.
"The oficial support site can’t be accessed from Brazil. You need to use a VPN (like Proton VPN)."
Support-03,
Thanks very much for the question and right answer for the problem "official support...".
ProtonVPN "free" allows the access.
Good job and I learn about it.
