I prefer to have Basemap - but I know many people delete it by accident or don't activate it - and I just tried a gmapsupp DEM map will also give shading to overview map. And yeah - maybe call it --dem-empty-dist
so you would have e.g. --dem-dists=19884,39768,53024,106048 --dem-empty-dist=212096 or --dem-dists=19884,39768,53024 --dem-empty-dist= 106048 not sure what values will work best. And yes I would expect only uknown or undefined heights should do the trick - but of course I do not know. With garmins usual approach i do guess it's possible to create it in a way that it switches off at some zoom level by inserting empty data.
