The drivers I mean are the ones recommended by Mint.
There is a way - use the frontend for managing restricted drivers, in Cinnamon it's called "Driver Manager" but it might be named something else for you since you use KDE (maybe Additional Drivers? It's been a while since I last used KDE.), I'm not sure. But this should let you pick between all the Nvidia drivers currently in the repository, and it recommends version 310.
If you can't find it, try running jockey-kde in a terminal. I think that's what runs it.
You can still manually install (I don't see why you couldn't, as long as you had everything you needed), though that's up to you if you want to do so.
