We’ll need to upgrade to Apache 2.4 to do that. It’s in the works, but it’ll take some time (and break some stuff :/). Once that upgrade is in place, a number of new SSL encryption configurations will become available, including a number of configurations which use ECC.
If you mean ECC SSL certificates, those are another matter entirely. Browser support for these certificates is extremely limited, to the extent that I really wouldn’t recommend trying to use one.
