Isn't this simply https://grass.osgeo.org/grass80/manuals/vector.html --> v.db.dropcolumn - Drops a column from the attribute table connected to a given vector map. --> It offers single and multiple column dropping: columns=name[,name,...] > I looked for that in the documentation but did not found it so easily.
