How to depend on a single crate from a github repo of multiple crates?

Hello, I want to use the crosvm_control library. You can see it here within the greater crosvm repo: crosvm/crosvm_control at main · google/crosvm · GitHub. As you can see, the crosvm_control library is just a crate WITHIN the crosvm crate.
Now the problem is: I just want the crosvm_control crate WITHOUT the entire crosvm crate in my project. How can I do this?

crosvm = {git = "https://github.com/google/crosvm.git"}

https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#specifying-dependencies-from-git-repositories

Cargo fetches the git repository at that location and traverses the file tree to find Cargo.toml file for the requested crate anywhere inside the git repository.

From my understanding that's going to include the entire CrosVM project which isn't desirable. Also I had tried this and there's an issue where whenever I try to reload my project I get an error that one of the packages audio_streams can't be found. I think this is because this package is only referenced in the [patch.crates-io] section which is a problem because there is no crates.io for CrosVM.

Generally you can't download only a subdirectory of a git repository. But that's only the download, cargo effectively ignores other crates unless they become transitive dependency of yours.
