Thank @jef-n, can you specify to which comment are you referring? or is the whole gist?

is there a switch to download a specific version of qgis?

No. But you can older versions from snapshots of the repo. Lookup from when a specific version is and pick a snapshot shortly after. Eg. in http://download.osgeo.org/osgeo4w/v2/x86_64/release/qgis/qgis-ltr/ has qgis-ltr-3.22.9-1.tar.bz2 from 2022-Jul-15 14:49, so if you pick a snapshot from http://download.osgeo.org/osgeo4w/v2/snapshots/ from shortly after by specifying (only) --site http://download.osgeo.org/osgeo4w/v2/snapshots/20220715-190611/ you get 3.22.9 as qgis-ltr. It's also possible to add it as "User URL" in the "Choose a download Site" page when using the installer interactively.

Thanks for the information @jef-n. But when I try to install the old version you mentioned, it always shows me version 3.28.15-1, I can click to change the version, but it should be a silent installation.

Then why didn't you specify --quiet-mode?
