Chrome ver.127 has the ja3 fingerprint of "772,4865-4866-4867-49195-49199-49196-49200-52393-52392-49171-49172-156-157-47-53,65281-35-27-51-43-23-17513-13-18-45-16-5-65037-11-0-10,25497-29-23-24,0".

By following the example, ec value of 25497 is not able to set. Can you give some guidence for modifying ec part?

Thanks!

X25519Kyber768 is a post-quantum algorithm, which hasn't been standardized by rustls (see this issue). I'm afraid changing this field without proper support by TLS library will cause bad incompatibility. However, you can still use the Unknown(u16) variant to set it to 25497, just at your own risk.
