Creating a 2 Day Lag in Looker Chart

[iglooburner]

I am trying to create a 2 day lagged report because my data is not complete until 2 days after the work date. 

For example, my chart today shows data through 3/22/2021.  However, 3/21 and 3/22 are not complete - which skews the charts.  I want to only have the chart showing through 3/20. 

Is there a way to automate so the chart always shows data that is two days old.  The default pulls in the most recent day which as I mentioned is not complete and skews the data.
