That's on the *client*. note that it's in ssh_config

	cat /usr/local/etc/ssh/ssh_config
		...
		Host *
		IdentityFile /usr/local/etc/ssh/ssh.client.ed25519
		...

On the *server*, in sshd_config it's 

	cat /usr/local/etc/ssh/sshd_config
		...
		HostKey  /usr/local/etc/ssh/ssh.server.ed25519
		...
