Scheduler: How to disable rowheadercolumn resizing?

This is a divider between row headers and the main Scheduler grid. At this moment, it is always resizable when you enable row header scrolling:

The rowHeaderColumnsResizable property enables/disables splitters between row header column titles (which lets you resize the individual columns).

Good to know the difference ;) Thank you!
