Hmm. Quoting `pkcs11-curr-v3.0`:

> Edwards EC public keys only support the use of the curveName selection to specify a curve name as defined in [RFC 8032] and the use of the oID selection to specify a curve through an EdDSA algorithm as defined in [RFC 8410]. Note that keys defined by RFC 8032 and RFC 8410 are incompatible.

An example then uses `edwards25519` as `CKA_EC_PARAMS`.
SoftHSM only supports OIDs for `CKA_EC_PARAMS` for EDDSA.
