[MM3-users] SUBSCRIBE_FORM_SECRET in MM3?

I've been looking into ways to prevent spam on my company's list, and one thing I came across was the SUBSCRIBE_FORM_SECRET option in the Mailman configuration, which embeds a CSRF token into the form, and prevents it from being submitted until five seconds after it renders, to keep bots from subscribing. Unfortunately, the information I found pertained to Mailman 2. Does this option exist in MM3 as well, or is there a similar option?
