Is it possible to tune parameters in a model built of blocks from the Simscape electrical library?

Attempting to use rsimgetrtp to build a Rapid Accelerator standalone executable target from a model of an electrical circuit. The parameters declared as tunable in the Model Configuration dialogue, but when executed the code returns warnings like:

Warning: Reducing expression 'Res92' in parameter field 'R' of 'Electrical10x10/PipeR92' to its numerical equivalent because this
field is marked not tunable. This expression resolves to tunable variables (Res92 (base workspace)). You will be unable to tune
this expression during model execution

Is it possible to declare Simscape parameters as tunable, and use a Rapid Accelerator target to avoid recompiling the model for each simulation?

Simscape™ run-time parameters are coded as variables with values that you can change before or between simulations without recompiling the model. Check the following resource to learn more about:
