Is it possible to manually manage a Solid State Hybrid Drive?

I'm about to buy a new laptop which has a SSHD. It stands for Solid State Hybrid Drive, which means it has a big, regular HDD with a small, usually 8GB SSD to cache frequently accessed files. Now since I'm a Linux user and I want pure SSD speed, so I thought it would be awesome if I could detach the SSD from the HDD and use it completely separate. I've googled for this topic, but could not find anything useful. According to Wikipedia there is a standard to communicate with the drives separately, but I may have misunderstood. Does anyone know anything about this topic?
