@PRNG12 Welcome to the forum!
The feature request thread (Options to disable or dismiss permanent "Change at-risk password" warnings) is not locked. However, you are probably seeing that you are unable to vote, because you are a new user. New forum participants need to have their membership status promoted from “new member” to “basic member” to get voting privileges; promotion is automatic after you have spent some time (<30 min) on the forum reading various topics and comments of interest to you.
In the meantime, you could add a comment to the feature request thread to describe your use-case and reasons for supporting the request.
