These G functions can always be programmed.
The default setting for NC Reset and/or NC Start is specified in machine data:

The following sources can initiate a retraction motion during thread cutting:
• Fast inputs (programming with

for "LIFTFAST" option)
• NC Stop
• Alarms that implicitly initiate the NC stop.
