./Device/Vendor/MSFT/Policy/Config/Cryptography/ConfigureEllipticCurveCryptography
This policy setting determines the priority order of ECC curves used with ECDHE cipher suites.
If you enable this policy setting, ECC curves are prioritized in the order specified.(Enter one Curve name per line)
If you disable or don't configure this policy setting, the default ECC curve order is used.
Default Curve Order
curve25519 NistP256 NistP384
To See all the curves supported on the system, Use the following command:
CertUtil.exe -DisplayEccCurve.
