no-unused-vars ESLint error

The issue is that typescript-eslint/no-unused-vars simply tag types and interfaces (that are imported or defined in the file) as unused, even if they are. Well for my specific case I ended up with this workaround

overrides: [
  {
    files: ['*.ts', '*.tsx'],
    rules: {
      '@typescript-eslint/no-unused-vars': [2, { args: 'none' }],
    },
  },
];
