My guess would be:

From:

https://www.samba.org/samba/docs/current/man-html/smbcontrol.1.html

"reload-config
Force daemon to reload smb.conf configuration file. Can be sent to smbd, 
nmbd, or winbindd."

or:

"--option=<name>=<value>
Set the smb.conf(5) option "<name>" to value "<value>" from the command 
line. This overrides compiled-in defaults and options read from the 
configuration file."
