Remove the space for the scrollbar in MenuTemplate

[ssongone]

First of all, thank you for the excellent MaterialDesignInXamlToolkit. I really appreciate it. However, when using the Menu template, I don't actually use many items, so there are cases where scrolling is not needed. Despite this, the area I've highlighted in the photo remains as extra padding, which is a bit inconvenient. Is it possible to remove that part when scrolling isn't needed? Or is there a way to choose whether to display it or not? If there's a way to remove it, could you please let me know?
