Is there a way to pin PDM version in pyproject.toml?

[netrix]

I have situation where I use PDM for my Python project. This project is hosted in Gitlab and has pipeline where I use a docker image with PDM (along with tox-pdm) already installed with version 2.2 (quite old).

Recently I had a situation where I need to update lock file (I've added some dependency) and I used newer version od PDM for it. After pushing changes to Gitlab the pipeline stopped working because it couldn't find my internally hosted packages (I've added tool.pdm.source to pyproject.toml). It looks like the lock file definition changed between 2.2 and 2.9 (that I've used to generate new lock file).

Is there a way to lock to the specific version of pdm in a way that pdm itself will throw an error if the version is not within constraints ?

This is the purpose of the lockfile version, but for some reasons, the version is defined badly and compatibility has not been fully guaranteed. We don't need another version.
