How to selectively suppress warnings displayed for a model in the Simulink Diagnostic Viewer in Simulink R2024b?

I am running a model in MATLAB R2024b that triggers multiple warnings in the Diagnostic Viewer. I would like to suppress all instances of one of the warnings. I did not find any parameter under Model Settings -> Diagnostics that controls the particular warning I am interested in.

Is there any other way to suppress specific warnings?

You can suppress diagnostic messages programmatically using the "simulink.suppressdiagnostic" function. However, this function may not work for all diagnostic warnings, in which case, you will get the following message:

The message identifier <warning ID> cannot be suppressed.

For these warnings, you can use the following workaround that utilizes Model Callbacks:

1. Add the following command to the "PreLoadFcn" callback of your top-level model: 

   old_warning_state = warning('off', '<warning ID>');

2. To restore the previous warning state after the simulation stops, add the following command to the "StopFcn" callback: 

   warning(old_warning_state);
