That is correct. Just do "scontrol reconfig" on the slurmctld server. If
all your slurmd's are truly running Configless[1], they will pick up the
new config and reconfigure without restarting.
Details are summarized in
https://wiki.fysik.dtu.dk/niflheim/Slurm_configuration#reconfiguration-of-slurm-conf.
Beware that you can't add or remove nodes without restarting. Also,
changing certain slurm.conf parameters require restarting.

However...
Given that the normal recommendation for adding/removing nodes safely is
to:
* stop slurmctld
* edit slurm.conf etc.
* restart the slurmd nodes to pick up new slurm.conf
* start slurmctld
I'm confused how this is supposed to be achieved in a configless setting,
as slurmctld isn't running to distribute the updated files to slurmd.
