Yes, it's possible. OpenSSL does not allow for per-protocol tuning, but there are some tricks you can use to achieve the same effect. In particular, GCM suites and SHA256/SHA384 suites work only in TLS 1.2, so if you put those first you are effectively prioritizing them on per protocol-basis.

Try this:

AESGCM:SHA384:SHA256:RC4:AES !aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!kEDH:!PSK:!SRP:!kECDH

This is from an example that's not related to PFS, so some tuning may be needed. The example is from my (free) OpenSSL Cookbook, which you can get from here:
