PKCS11 sis supported by transit

I am going through https://www.vaultproject.io/api-docs/secret/transit#signature_algorithm
Found that it supports ED25519 and ECDSA curve. Is it pkcs11? Can create ECDSA using the P-256 elliptic curve and use as my ethereum pub/private key for signing?

From what I know transit engine is not a pkcs#11 engine. The only engine which supports pkcs#11 standard is KMIP KMIP - Secrets Engines | Vault | HashiCorp Developer and provides the access through pkcs#11 provider plugin PKCS#11 Provider - Vault Enterprise | Vault | HashiCorp Developer and only supports for asymmetric encryption RSA. ECC and ED curves are not supported…

P.S. But I’m not a vault developer so I can be mistaken
