Raster Extraction

I have been trying to extract portions of my DEM with water body features. Ideally, I should be using the extract by polygon tool and setting the extraction area to outside. However, because I have complex polygons as water bodies, for me to input the XY coordinates of the vertices of each polygon would take me days as I have over 41,000 points.
I can't use the extract by mask because it doesn't allow you to set the extraction area.

Is there a quick way to erase complex polygon features out of a DEM?

Thanks for your help.
