How can I use alr publish --tar --skip-submit on a git checkout of a commit?

Azure Pipelines are doing this to ensure that the branch did not change during the run of the pipeline.

Right now I get the following error:

ERROR: /home/vsts/work/1/s: Your branch is ahead of remote:
ERROR:    Please push local commits to the remote branch.

I tried alr --force publish --tar --skip-submit, but this did not help anything.

In the code of alr I found https://github.com/alire-project/alire/blob/16b060b385f10932df967a7e9be1792842f24975/src/alire/alire-publish.adb#L217 and traced back from there and did not find a way to skip this check.

However, it is hard to believe that no one needs this.
