Where to find the settings about disabled built-in extensions in VS Code?

I usually disable some built-in extensions in VS Code that I do not use, I use Code Setting Sync extension to sync my VS Code settings.

But it does not sync my settings about disabled built-in extensions, I suppose that extension ignores the file that contain those settings. So I am thinking about adding it manually as describe here. But I was not able to find that file which stores those settings.

So where can I find that setting file?
