How to Buy Bitcoin Anonymously

I am trying to find clear and reliable information about buying Bitcoin anonymously. Many exchanges now require full KYC and ID verification, and it is hard to know what options still exist.

I am not looking to do anything illegal, just to protect my privacy. I often see terms like anonymous Bitcoin, no KYC exchanges, private Bitcoin purchase, and peer to peer Bitcoin, but most explanations online are unclear or outdated. Is it still possible to buy Bitcoin without full verification, and are there any trustworthy platforms or methods? Any guidance would be appreciated.
