No, short of some other intervention—DACA lives beyond March 5th.
Isn't Mar 5 the date the mechanism for extending the dreamers stay ends ? Even if the mechanism stays in place what's to stop them from just not granting the extensions ? It seems to be just an administrative thing. Kind of like the visa brouhaha, if a visa isn't granted for any reason it stops legal entry, the same way if a DACA extension isn't granted then it's deport time.
