NVidia (and AMD for their own line) did not talk about these in the public much as they were really bad PR during the worst moments of the gpu shortages.
To the point that they never even updated the site for the later/better models (like the already mentioned 170HX). Only mentions of it you can find are the sellers you have to go to to get one (NVidia did not sell these directly to anyone as far as I know)
AMD developed a line of mining cards as well as well, and also some PS5-based mining rigs from asrock (it's a PS5 apu reject on a motherboard with VRAM...) that utilized AMD BC-250 mining processors.
