Auto complete on the first tab if even it's ambiguous

Environment

% typeset -p1 VENDOR OSTYPE ZSH_PATCHLEVEL _autocomplete__funcfiletrace
typeset VENDOR=apple

• Operating system: MacOS Sequoia 15.2
• Terminal emulator: iTerm

Steps to reproduce

% cd $(mktemp -d)
% mkdir something1
% mkdir something2
# When type "cd" and hit "tab", it will auto-complete entire in the first time even it's ambiguous.
% cd something1/

I'm wondering if I can disable that feature or not. It's really annoying to me. I tested it and show the same behavior on Linux. Sometime, it makes faults when I type the path very fast.

There's a setting for this and it's documented in the Readme.

Could you please specify the right command and detailed guidelines for that?

I've tried to add the following configuration by the souring auto-complete command in my .zshrc. But it's failed.

# all Tab widgets
zstyle ':autocomplete:*complete*:*' insert-unambiguous yes

# all history widgets
zstyle ':autocomplete:*history*:*' insert-unambiguous yes

# ^S
zstyle ':autocomplete:menu-search:*' insert-unambiguous yes
