Where can I buy small amounts of Ethereum without having to use know your customer verification, or having to use a custodial account?

I can’t use kyc because of age, but I want to get into investing, starting off with small amounts of ethereum, because I feel like that is what I would want to invest in most, this post is not so people can give me financial advice, so please keep coments to the same topic, all I want is to know a place where I can buy small amounts of ethereum (like $50 worth AUD, which would be about 35 USD) without having to use kyc, thanks for help in advance

If I can not buy ethereum straight and it would be easier to buy another crypto like bitcoin, then transfer that to ethereum using something like exodus wallet, where would I go about doing that?

Dont want to use p2p transactions or kucoin, or one of those crypto atm things
