Here's an example how to do that:
pdsargs = pds.create()
pds.putString(pdsargs, "name", "cdm")
pds.putString(pdsargs, "section", "/disk/alarm/fixed/#boot")
res, rc = nimbus.request("/domain/hub/robot/controller", "probe_config_set", pdsargs)
This script would remove the section "#boot" (boot section on linux machine) completely from the config.
