Maybe an archaeologist or geologist could give you a more accurate answer, but the simplest way to 'remove vegetation' from a scan in CloudCompare is to use the 'Height grid generation' tool ("Tools > Projection" menu). Use a rather large step and select the 'minimum height' as projection type (so as to only keep the ground points). Select also the 'leave empty' entry for the 'fill empty cells with" option.

However I believe there's better ways (and surely better tools) to do this.
