How to override the source of external dependencies? similar to patch.crates.io

I have a Bazel/rules_rust project without a Cargo.toml and I was unable to find how to override the source of a dependency.

When I crate a spec pointing to my fork, it works for direct dependents. When other crates depend on the crate I forked, they get a different version from crates.io.
```
crate.spec(package = "tokio", git =...) # <- works for direct dependencies
```

How can I define a specific version and override it with a git repo?
Something like
```
crate.spec(package = "tokio", version = "=1.36.0",...)

git_override(
module_name = "tokio",
remote = "...",
commit = "...",
)
```
