It always depends on what you want to do. My reply at [Question about understanding irfs in dynare](https://forum.dynare.org/t/question-about-understanding-irfs-in-dynare/10622/4) should be useful to understand different approaches to linearization an log-linearization. The short answer to your question is: you can work on a variable by variable basis. Variables already in percent or with steady state 0 can be linearized while everything else is log-linearized.
