There's a 1.5.1 tree at https://github.com/raspberrypi/pico-sdk/tree/1.5.1 but I have no idea how one would install that rather than the latest 2.1.2 master.
I recall there is a way to revert a latest master to an earlier version in-place, or within a copy of it. Using 'git checkout 1.5.1' rings a bell but I may be wrong.
This looks promising but no idea of what additional work you would need to do ...Leave the '-l' out to unzip to disk.
That seemed a little small - 11 MB unzipped, but maybe the other ~600 MB I see is under '.git' and 'lib' ?
But it's not a 'git repository' so 'git submodule update --init' doesn't fetch those.
