try

condor_config_val -startd -rset "Start = FALSE"

It's not terribly clear if the reconfig is needed for rset? or if it
works for persisted values

if not then you could try something like:

condor_config_val -startd -set "OldStart = ${START}"
condor_reconfig
condor_config_val -startd -set "START = <whatever>"
condor_reconfig

the later 
condor_config_val -startd -set "START = ${OldStart}"

This may not work though since you may simply end up with the line
OldStart = Start
rather than
OldStart = <whatever start was>

This could be worked around with a script which evaluated START,
copied the result X to another command condor_config_val -set
"OldStart = ${X}"

depends how complicated you want to make it.

I set up my team with the following condor_config.local settings

# work between 8am and 8pm Monday to Friday
AllowJobOverrun = True
HappyToRunAlways = False
OnHoliday = False
WorkHours = (( (ClockMin >= 480 && ClockMin < 1200) && (ClockDay > 0
&& ClockDay < 6) ) && ( $(OnHoliday) == False ))

START = $(START) && ( $(HappyToRunAlways) || $(WorkHours) == False )
PREEMPT= ( ($(HappyToRunAlways) == False ) && ( $(AllowJobOverrun) ==
False) && $(WorkHours) )

then they simply alter AllowJobOverrun, HappyToRunAlways, OnHoliday as needed

and issue a condor_reconfig...
