Over many years I have collected freely available Nik Collection presets (recipes) from around the web. They are mostly for Colour Efex Pro 4, then Silver Efex Pro 2, and a smattering for HDR FX and Analog FX.
Persevere when you install. I should spend some time sorting them properly. If they do not install in one package - then clearly they aren’t for that package - so try the next one, and so on. Here is the Google Drive link.
