bitbucket pipeline to push commits to another repo

Question

So this is the scenario i have right now, we have a repo (boilerplate) that contains our infrastructure code, docker files, and pipeline scripts, each time we create a new project we copy this repo to a new repo.

the issue is this when we make a change in the boilerplate repo, we have to manually make the change in all our projects and i'd like to automate this process.

is it possible to create a git hook or a bitbucket pipeline to automate this process?
