Unfortunately, there isn't a way to ignore the model callbacks when building a model as of Simulink version R2023a. To work around this issue you can create a MATLAB script that 'strips' or comments out the callbacks.
For example, below is an example to strip the 'InitFcn' of a model (saved in 'mdl') and then put it back:
>> origCB = get_param(mdl,’InitFcn’);
>> set_param(mdl,’InitFcn’,’’); %Disable initFcn
>> % Do something here
>> set_param(mdl,’InitFcn’,origCB) %Enable initFcn
If you have many callbacks, you can find them using the 'Callback Tracer'. You can also find the slowest callbacks and only disable those. Please refer to the following documentation page for more information on the 'Callback Tracer'
