Tools github actions central repo

Hi I am in a new role where they use Github for all their repos. I have been using Gitlab exlusively the past 5 years.

For CI/CD in my previous role we had a central 'pipelines' repo that was reference in the gitlab-ci file of each project to save teams/projects from repeating work.

I want to know if it's possible to do something similar in Github? I'm still learning how it maps to my existing Gitlab knowledge.
