have you tried bisq?

You can buy Azteco Bitcoin gift card too. Available on chain and off chain.

P2P, maybe checkout local meet up. nostr:nprofile1qqsyx53h3h7ec4fwlspjq0kqec5gv54t7rc48xdtq6q4y94wsw4fnjqpr9mhxue69uhkummnw3ezuun0vfhhxct5wvhx7un89uq3wamnwvaz7tmjv4kxz7fwxpuxx6rpwshxxmmd9ugper8t

If you purchase with your bank account or card through a centralised service, it's not non KYC. If that's your only option, though, better to buy via robosats or bisq, as it's peer to peer, i.e. only you and the seller would know your fiat payment was meant for buying btc.
