No.  V1.x doesn't support it under DPMI environments (ie windows, etc) either

It would be virtually impossible to provide this sort of access under a
DPMI 0.9 host.  This could be done with a DPMI 1.0 host - but the only
one out there is currently 386MAX.  The source for CWSDPMI is available,
so you could add some custom extension to it for this purpose.
