How can i make changes in the Admin Core functions (deactivate net price)?

I’m searching for a solution to the deactivate the net price , which is a backend core function, through a module/plugin, to ensure the system is updateable in the future.
I’ve tried following solutions with no success:

  • tried to make a child theme of admin
  • tried via PlugIn to manipulate the block

Is there any hint or option to do this task?

thanks and regards

As you wrote… net prices are in the Core. The Admin theme is a template.

Thats not possible. You would have to rewrite the Core.

Still, I do not get it. Why can’t you update your system with net prices activated?
