Hi Gert-Jan,
QGIS cannot work without the GDAL/OGR library.

The OSGeo4W *.msi installer installs all the needed libraries (like 
GDAL/OGR, GEOS, PROJ, Qt, Python with some modules, ...) plus a lot of 
not strictly needed tools and libraries which are however very useful 
(like GRASS-GIS, SAGA-GIS for QGIS 3.28, various GDAL/OGR plugins and 
various additional Python modules).

Using the OSGeo4W Network installer osgeo4w-setup.exe, the user can 
install all the same packages installed by the .msi installer or only 
the needed packages.

The *.msi installer is actually a stand-alone / all-in-one version of 
the OSGeo4W Network installer.

Best regards.

Andrea
