Any guides on how to do this?
You want to use a KYC-free, no-registration coin changer. flyp.me seems the best right now, but these services tend not to last long KYC-free.
Note that although bisq is decentralized and therefore more likely to survive long-term, it's pseudonymous, so an observer can link together all of your bisq transactions. This is very bad for privacy.
Binance should also work fine, right? Even though they require registration, I think you could easily use fake information and just create multiple free emails through email services like ProtonMail[1]. As far as I know they don't lock suspicious accounts, though I'm really not sure.
