Disable Change Password SMS Text

Version SSPR v4.5.0.0 b51 r7db460d8

Is there a way to disable the sending of the txt after a user successfully changes their password. We have the email option enabled and we don't want to continue to use SMS for some features, but just not for this action. 

Under the "Change Password SMS Text" the default verbiage of "You have changed your password.If you did not initiate a password change please contact your help desk immediately." is listed and it cannot be removed. I initially was thinking I could just remove the verbiage from here and it would in effect disable the sending of it, but with no value in here, the 'ok' button cannot be clicked.

Also under 'Post Password Change Actions' , there is nothing defined.
