I just see — this functionality was already done.
Unwanted commands are defined in command_groups.conf for group 1 (normal user can be an operator on a new created channel):
1 /kick /ban /unban /op /deop /aop /voice /devoice /vop /devop /tmpop /moderate

I'm not sure how better hide them. For instance, if define these command list for operators in code (to check user operator or not, and do not display them) then it will be defined in two places twice (config and code), that is not good.

My suggestion is do not hide them but add sections. There a new special symbol can be added in bnhelp.conf @ that designates a section title (or just use brackets [Title]).
Then output of /help will be like this:

[Info commands]
/games
/users
/time
/uptime
/tos
/motd
/news
/version
/license
[Self commands]
/stats
/icon
/clan
/friends
/ping
/dnd
/away
/me
/chpass
/timer
/logout
[User commands]
/msg
/reply
/ignore
/whois
/watch
[Operator commands]
/kick
/ban
/topic
[Admin commands]
/shutdown
(and all that with cg >1)

List of commands will be more convenient, it will be easier to find a command.
Normal user (cg=1) will see all the sections except Admin commands.
