yes, and a lot of it's open source. The main issue IMHO is that git doesn't scale for a monorepo. A monorepo wants to spread a single virtual repo over a large number of devices, with no device having the entire repo. In contrast, git wants to do the opposite: it's built for a large number of devices to have the same copy of the entire repo. But aside from tooling and needing a horizontally scalable VCS, there's also the cost and engineering resources required to keep the cluster running, available, and high performance.
