Interaction between USD CbCR and Pillar 2 safe harbours

Summary:

To ensure CbCR values meet qualifying criteria, post-translated (USD_reporting) values are sourced from FCCS for financial values in table 1 - Revenue and profit being the important ones here. These are then automated into the CbCR table 1.

We have non-USD base entities, so the CbCR scenario fixes all exchange rates at 1:1 to avoid any unintended translation.

This works, but my concern is for the Pillar II safe harbours piece. This is carried our in actuals where exchange rates are not 1:1.

Is there any way to ovverride just the De minimis / ETR CbCR codes in the safe harbours form?

Say for arguments sake we created a new scenario for pillar 2 and fixed the exchange rates at 1:1, the aggregration through the GloBE income / Covered tax forms would not work so this is not viable.
