gh config set telemetry disabled (starting from version 2.91.0, which this announcement refers to)
gh version 2.90.0 (2026-04-16) https://github.com/cli/cli/releases/tag/v2.90.0
$ gh config set telemetry disabled
! warning: 'telemetry' is not a known configuration key
Also note that even though you get a warning about an unknown config key, the value is actually set so you're future-proof. Check `grep telemetry ~/.config/gh/config.yml`
What's strange is if you check your `~/.config/gh/config.yml` it will put `telemetry: disabled` in there. But it will put anything in that `config.yml` lol.

But in my config.yml is
this-is-some-random-bullshit: aww-shucks
