It appears that template like you to have both enable and enable secret password and it doesn't allow to change enable secret if you do not have enable password defined, is it true?
I want to change enable secret using Netconfig where it can update DCR for me and I don't have enable password in my devices and I don't want one.
No, you must NOT check that box. That box is only for the enable password. The enable secret password will automatically cause DCR to be updated.
