If you have access to R statistical software, you can try package 'elevatr' (https://cran.r-project.org/web/packages/elevatr/index.html). The function getData() of package 'raster' can only download tiles (if parameter 'name' is set to 'SRTM') or DEM for countries (if parameter 'name' is set to 'alt').
