Is this done by intercepting the API calls made to the GPU, or by directly modifying the game binary instructions?

Modifying binaries (on disk or in RAM) would be detected by anti cheat mechanisms. Most likely they change how to interpret a certain sequence of API calls or replace shaders with their optimized versions.

Yeah, i guess i shouldn't have said "bug" in the traditional sense. More like "lets rewrite the gpu calls for this game instead of getting 53 avg fps, they now get 60 avg fps) since we (being nvidia) knows it better.

Most likely when a game is released, the team that build it disbands to work ons omething else and wont have time for performance hacks like this.
