No: Exim doesn't read the certificate until the last possible moment, at
which point it has thrown away all privilege. You can restrict readability
of the certificate to the Exim user to hide it from other users.

(It would probably be safer if Exim had an option to load the certificate
at startup, and prompt for any passphrase; the cert would then be secure
against compromise of the exim user.)
