How to change ownership of a deploy key?

I recently change the git server on my work from gitolite to GitLab. Everything went smoothly. We decided to use deploy keys until we begin to use CI/CD. So, as the main responsible for the process, I created all the deploy keys and assigned them to the projects. Our deploy method creates a tag on every pull done on production, so we know who did it and when it was done. Works great for our porpuses. Now that we started to use the new environment, I noticed that all the tags are being pushed on my name, which makes sense, but is not ideal.

Since we have more than 60 projects and would be painful to recreate the keys and assign them to each project, is there a way to change de ownership of the deploy keys to a default account? If not via interface, directly on the database?
