In your Wow Addons folder, delete GS-Darik’s macros. You just want “GS-Core” and “GS-SequenceEditor”. You can also create your own macro folder and place/make macros in there, but that is optional.
You could just disable GS-DraikMacros in your addon list. Deleting it means it will come back next update.
If you add in other mods Like the HP Macros or GS-Darkrams or a thousand of your own macros then the Disable Macro in /gsse will allow you to disable ones you don’t want while keeping others from the mod pack. This will delete the macro stub and will also prevent the check for the macro stub and recreating it.
You can also turn on the function to allow overflow from Personal Macros to Account Macros. I would look at disabling rather than enabling this.
