If the links above don’t work, driver packs are a bit harder to locate than they are for Dell and HP. You have to hit the Drivers & Software page on the Lenovo site, then walk through their wizard to identify the model of PC for which you want drivers. Once you do that, you can jump to the Enterprise Management spot and grab the ConfigMgr Packs for the various processor types.
