Value state without a message on focus

[i069626]

Hi experts,

Is there a way to set a value state like 'Error' without having a value state message show up on focus?
Even setting the value state message to an empty string leads to a UI that looks like this ->

For the inevitable question of why you would ever need to show an error without an error message ->
We need to have different controls for date and for time. Instead of showing 'Enter a date and time' on both controls we'd like to just use a MessageStrip with that information below the two widgets.
I know there is a DateTime picker which combines date and time but our use case mandates that they are different controls.

Is there a way I can set the value state to 'Error' without having an associated value state message show up on focusin?
