How can I Disable Log signal data of a local and output signals of a state machine in model explorer in Matlab 2019b

I have a state machine in my core model which has local and output signals Log signal data enabled. I want to disable that option and need to save the model. I have used the below code but still I was not able to save the changes to the model.

mdl = 'Modelname';

mi = Simulink.SimulationData.ModelLoggingInfo.createFromModel('mdl');

for i = 1:numel(mi.Signals)

mi.Signals(i).LoggingInfo.DataLogging = 0;

end

set_param(mdl, 'DataLoggingOverride', mi);

You can follow the steps below to disable log signal data option as follows:

• Open the model in Simulink.
• Open the Stateflow Chart from the model and now open the Symbols Pane from the Simulation tab in Prepare Section.
• Similarly Open the Property Inspector from the Simulation Tab in Prepare Section.
• Now select the data or signal whose Logging is be removed from the Symbols Pane.
• Now In the Property Inspector, under Logging, uncheck the log signal data check box to disable the logging.
• Now save the model by pressing ctrl + S or using the save button present in the Simulation Tab under File section.
