2020 GD 20BHE - Adding a Privacy Curtain

[xxDRBxx]

Looking for advice on the possibility of safely adding a privacy curtain to the back room area of my 2020 20BHE. I know there are other models within the Imagine XLs line that have a full width privacy curtain, but Im not sure about mounting and damaging anything in the ceiling.

I have attached a pic for reference of the floor plan.

Can I add a GD privacy curtain from a 21BHE or 22MLE safely without damaging anything or voiding warranty on anything?

Thanks - Dan
