Is this what you're looking for?
 from ccp4.setup :

### CCP4_OPEN ###
# CCP4_OPEN may be set to 'UNKNOWN' rather than 'NEW' to stop open failures
# for files opened as NEW that already exist.  Novices should use 'NEW' to
# avoid inadvertant over-writing of existing files -- in this case any such
# attempt will be a fatal error.
#
  setenv CCP4_OPEN        UNKNOWN               # edit this if necessary
