The Nazis literally used custom made IBM punch cards to keep records of their undesirables. I know society at large was mostly unaware of computers, but did they did play a role in WWII. We see cipher devices like Enigma in historical documentaries and fiction, but we don't see the computers that calculated bomb and rocket trajectories, and least of all the Nazi's database which seems quite well buried in footnotes, though it was critical in the holocaust.
I still stand by the answer to your likely rhetorical question is that it wasn't really hidden that much it simply was utilized so little that the exact sites and personnel that used computers of the time are incredibly few in number, so while easy to document and possibly quite impactful: it also wasn't a very big part of the era as a whole.
