I’m sorry, I don’t fully understand your question. Are you wondering how to create an Ed25519 key using `ec2.KeyPair`?

Sorry, I've edited the msg,
Yes, I want to create an Ed25519 key using ec2.KeyPair

*EDIT:*
if I pass the ed25519 key, it's chosen on AWS this type (i think that need to elaborate it in docs)
Solved!
