Yes, you can. If you disagree with Apple's System Integrity Protection, you can take two whole minutes of your life (if even up to that, considering how quickly OSes boot these days) to turn it off permanently and mount the entire drive as read-writeable. For some strange reason, though, I tend to encounter far more people complaining about it than actually taking the steps needed to fix the "problem".
