Yes:

db.connect driver=dbf database='$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/'

which sets the default database connection to dbf. Note the difference
between db.connect and v.db.connect. In your case, you would need to
run db.connect immediately after the mapset is created, before any
vector data are imported in the temporary mapset.
