There are no property setting to manage this.
But I think it would be straight forward to set up a usercontrol that handled this for you. You could dock panel right and bottom. Then in the bottom panel, dock another panel left and dock fill your horizontal scrollbar. Then in the right panel dock two panel top and bottom, and then dock fill the vertical scrollbar. By sizing the top and bottom panels in the right panel, you can dynamically position the vertical scrollbar. By sizing the left panel in the bottom panel, you can dynamically position the horizontal scrollbar. Then you can dock fill a grid in the user control and set it to use these disconnected scrollbars.
Then each time you need one of these special grids, use this usercontrol instead of the GridDataBoundGrid. You can expose a public field or property on the user control to directly access the grid. Below is a little sample showing what I mean.
