How can I tell EmbeddedCoder/SimulinkCoder to not evaluate expressions containing Matlab tunable parameters when generating C-code from Simulink?

Hi, I have a saturation block in Simulink where I set upper and lower limits based on a tunable parameter and have the output port generated as global variable:
In the generated C-code the lower limit expression is evaluated to:
srt_gyroXsaturated = rtU.gyro_X >= srt_gyroLimitX ? srt_gyroLimitX :
rtU.gyro_X <= -0.349040151F ? -0.349040151F : rtU.gyro_X;
What I want is that '-srt_gyroLimitX' is not evaluated to '-0.349....' but left "as is" in the generated code. How can I achive that?

For tunability in code generation, the parameter needs to be a variable. Parameters specified as expressions are evaluated and inlined. You could specify the limits as 2 separate variables to ensure that code generation preserves the tunability.

Same question as Matphree: how to prevent block parameter evaluation in the generated code?
