Hi @hua
I understand that you are looking to disable the Simulink overview feature which is displayed when we zoom into a Simulink model.
Currently, there is no option to disable this overview. I was looking to perform the same action a while ago and came across the following MATLAB answer thread: https://www.mathworks.com/matlabcentral/answers/1627565-how-do-i-disable-the-new-simulink-zoom-overview
Hope this helps!
