Disable Confirm Auto-Fill Pop Up

I think I can change it from configuration settings using the client--> Metadata card option but it is giving me an important read message saying I could mess up the vault. 

The warning when you enable centralized client setting management is there in case you have for instance distributed some client settings to users' computers via other methods such as GPO. Enabling client settings via Advanced Vault Settings will overwrite these and you need to plan the change carefully. If you don't have such customizations, there's nothing to worry.
