This question is confusing.

Are you asking whether you can phase modulate a carrier and transmit
it with an RFX board?  If so, the answer is yes, of course.  However,
you would do this by manipulating a baseband signal on the host PC in
GNU Radio in such a way that when it is mixed with the carrier in the
USRP, phase modulation results.  Thus, the "(not baseband)" part
doesn't make sense.
