unselect automatic design load combinations

I'm working on a project and I need to unselect automatic design load combinations.
I can not find the related code.Can anyone help me?

In the concrete/stell design selection (whatever you want) select the view/revise preferences option. This is where you choose the code and the design preferences.

To deselect the auto load combinations check the "design load combinations selection" and untick the box "Automatic ...".

To manually edit these combinations, click the "Set automatic design load combination data".
