I doubt cdo can convert to geotiff (in fact I am sure of ir, as I was
having a discussion with the devs about it some months ago).

Perhaps you are confusing with other software (or a really old
versions used to do that).

However, it can convert to netcdf which is well supported in gdal/qgis.

The proper (current) page for cdo is  https://code.zmaw.de/projects/cdo/
