Finally there is a single build for all CUDA versions.
Also, we added Kaspa and now nanominer suports dual, triple and quad mining.
version 3.8.0 in triple maning mode does not work well

there was some kind of failure (perhaps from the program itself or from the fact that one of the cards number 2 fell off) after which everything went wrong, the found shares were not accepted, as a result, more than six hours of work wasted

Use other miners, nanominer is not worth. BZminer, teamredminer, srbminer, rigel, gminer all can handle mining 3 coins at the same time with a much higher hashrate and for sure a much better support.
and so I used other miners, but in a single version, apparently other options need to be considered
