Waterfall Chart : (1) Hide and Add +/- sign from data labels (2) Provide Conditional Formatting option Data Labels

So , I was tasked to simply remove the minus sign from the non-pillar bars of the data values from the waterfall chart. But this was impossible .

From what I have seen online I could have used conditional formatting with DAX to merge the minus sign with the background. But that requires the chart to have a data label conditional formatting to begin with.

OR

This could be simply resolved if you have an option to simply hide/disable the minus sign under the data label part of the format option.
