No, the immune system is not controlled by our microbiome. The microbiome interacts with, and modulates the immune system in various ways, but it's hardly "controlling" it. There are germ-free animal models with sterile guts, which demonstrate that you can live without a microbiome - of course not 100% healthy, but they can still live and reproduce.
The immune system is modulated by a lot of things: circadian rhythm, environmental stress, nutrients, etc. Yes, the gut microbiome is one of them. But let's be a bit more nuanced than Joe Rogan or The Liver King.
