In fact, as far as I know, we cannot use it directly, as I see in some posts that some countries outside of Brazil accept it, in this case I buy hive with HBD and send it to Binance, from there I send it to my account via PIX, which is a transfer that we make and pay a fee of R$3.50 reais. There are other ways too, but I have always sent them to Binance. Regarding gift cards loaded with dollars, I don't know this process, it would be something I would have to look into to find out if they work here.
