Sure. From the xset man page:

       -dpms   The -dpms option disables DPMS (Energy Star)  fea-
               tures.

       +dpms   The  +dpms  option enables DPMS (Energy Star) fea-
               tures.

       dpms flags...
               The dpms option  allows  the  DPMS  (Energy  Star)
               parameters  to  be set.  The option can take up to
               three numerical values, or the `force'  flag  fol-
               lowed  by  a DPMS state.  The `force' flags forces
               the server to immediately switch to the DPMS state
               specified.    The   DPMS   state  can  be  one  of
               `standby', `suspend', or  `off'.   When  numerical
               values  are  given, they set the inactivity period
               before the three modes are activated.   The  first
               value  given is for the `standby' mode, the second
               is for the `suspend' mode, and the  third  is  for
               the  `off'  mode.  Setting these values implicitly
               enables the DPMS features.  A value of  zero  dis-
               ables a particular mode.
