Multiple Row Card - Hide Blank Values

Hello,

I have a multiple card row, with a few metrics.

And depending on which month is selected, some metrics will not be considered (their result will be blank).

I tried using condicional formatting, but it requires a specific field, and here i have many fields.

Also tried replacing the blank with 0, using the +0 at the metrics, but didn't work either.

How can i not show the Metrics that the value is blank (or 0)?

The expected result is this: (i just removed the metric, por example purposes)

Thanks in advance!
