Renovate can upgrade dependencies in `conanfile.txt` or `conanfile.py` files and also updates `conan.lock` files too if found.

How it works:

1. Renovate searches in each repository for any `conanfile.txt` or `conanfile.py` file
1. Renovate extracts existing dependencies from:
   - the `[requires]` and `[build_requires]` sections in the `conanfile.txt` format
   - the `requirements()` and `build_requirements()` functions in the `conanfile.py` format
   - and the `python_requires`, `requires` and `build_requires` variables in the `conanfile.py` format
1. Renovate resolves the dependency's version using the Conan v2 API
1. If Renovate finds an update, Renovate will update `conanfile.txt` or `conanfile.py`
1. Renovate also updates `conan.lock` file if exists
