I do not see it in the free plan. Per the screenshot in the article, on the bots section I see two toggles - Bot Fight Mode and Block Bots. Below these toggles I see

1. A call to action Upgrade Plan for a Super Bot Fight Mode (pro or business)

2. The link to https://developers.cloudflare.com/bots/plans/ which does not mention (yet) of this new security setting.
