How to override warning in Taskwarrior?

I have the following output whenever I issue task:

It's because I put the config and data files in non-default external location specified by $TASKRC and $TASKDATA environment variables of Taskwarrior.

How could I make task to be quiete and not warn me everytime.

I'd like to find the command line switch to make it quiet for the issueing time (once) and the also config file option to make it permanent, if any.
