No.
Some drivers support compression directly.
You also may have a proxy type (type 3) driver and this could possibly support compression as well (you seem to mention this).
There is no "generic" solution though as the actual protocol used by a specific driver is not generic but specific to that server.

Do you know if any oracle driver support compression?

Yes, that what I mean, sorry for poor terminology. Do you think proxy type driver like that exist?
