As far as the standard NDIS OIDs are concerned, no, NDIS does not
currently provide a mechanism to control the authentication and
association process in a way required for 802.11r. In other words, this
would require vendor specific OIDs to be defined and changes to both the
driver and wpa_supplicant driver wrapper.

Initial mobility domain association could work with driver_wext, but the
actual use of FT protocol would likely require changes in driver_wext.c.

I have tested only against hostapd myself, but other people may have
tested against other implementations.
