Disable maximize button of WPF window, keeping resizing feature intact

Disable maximize button of WPF window, keeping resizing feature intact

So WPF windows only have four ResizeMode options: NoResize, CanMinimize,
CanResize and CanResizeWithGrip. Unfortunately, the options that enable
resizing also enable maximizing the window, and those that don't are
useless to me. Is there an option to disable the maximize button while
keeping the resize feature?
I'd prefer solutions that don't involve WinAPI stuff.
