How to clip a DEM to include data only OUTSIDE polygons

I have a DEM and I have a shapefile showing polygons that represent mounded features. I want to create a DEM which has 'holes' in the data where the mounds occur. This is because I wish to regrid it and then subtract this hypothetical bathymetric map without mounds from the original in order to work out the mound heights.

Also if you can think of an easier way to calculate mound heights please let me know.

Thank you,
