Are you referring to Poetry ?

But same question on poetry also interesting

If you set the package_manager to peotry then it will only use the lock files

If you clear the "Installed Packages" section, it will just use the "requirements.txt" in the repository itself.
What's the specific use case, and the problem we are trying to solve?
