How i can delete file and all this history?
I found this but i think is only for local git: https://myopswork.com/how-remove-files-completely-from-git-repository-history-47ed3e0c4c35

Hi @subscriptions
as the page describes, you do the changes in your local workdir and then use push --all to overwrite history in gitlab.
