Best way to swap BTC for other crypto

Been holding some Bitcoin for a while and looking to diversify a bit without going through centralized exchanges. Every platform I check wants ID, selfies, proof of address the whole thing.

What's the cleanest way to swap BTC for something else (ETH, SOL, etc.) while keeping it non-custodial? Ideally something that connects straight from wallet and doesn't require signing up. If you've done this recently, what worked for you?
