Question About Buying BTC in USA

Is there a way to buy BTC & other coins with Debit or Credit Cards in USA without any KYC or documentation ?

(Background : I(37M) am a old school Financial Consultant from India. One of my NRI client's son wants to get into the web3 thing and wants to buy crypto. My client has 2 specific requirements: (1) The purchase should be through Debit or Credit Cards ; & (2) There should be no KYC as his son is a Minor and he doesn't want his name directly anywhere in this.)

Any help or guidance is appreciated.
