If no one knew about inflation, would inflation take place?

I’m not an economist and would like some insight into this thought experiment. If people, the news, social media, etc. suddenly stopped talking about inflation, would inflation still take place? Inflation is a money supply issue(?) so, if no one knows about the money supply, about how the government is printing and printing, as if the printing took place completely in the dark, would the price of goods still increase? What forces would drive this price increase? Thanks!
