How to exclude Simulink blocks from code generation?

Basically, my project is: to acquire data from a USB webcam and perform some color thresholding and object tracking. The output obtained from these blocks is then given to Arduino for hardware implementation. Now if I directly build the model, it generates code for the whole model and then deploys to Arduino board which is basically consuming more memory and making my model to run at a slower speed.

How can exclude these blocks(computer vision and image processing toolbox) from code generation?

I can use the following statement to ignore code sections when using Matlab Coder, but it does not work with PLC coder.

if isempty(coder.target)

% Place code here you want to exclude from code generation

end

Is there a way to ignore code sections only during PLC code generation? Is there a way to detect in code that PLC Coder is operating on the code?

If you want to exclude some blocks from Simulion and Code Generation, then you can comment them out.

As far I know, there is no way to exclude some block only from code generation.

I don't want to exclude these blocks from Simulation. Just want to simulate the model without generating any code for these blocks.
