You can just reset the appearance for UIDocumentPickerViewController only by putting this code somewhere in your application:didFinishLaunchingWithOptions: function and the bar buttons will return to their original blue or you can set any other color of your choice. The bar color, on the other hand is not customizable.

if #available(iOS 11.0, *) {
    UINavigationBar.appearance(whenContainedInInstancesOf: [UIDocumentBrowserViewController.self]).tintColor = nil
}
