NIFI Registry with GIT as persistence provider without using GIT credentials

Hello,

We have a nifi registry running under AWS ECS and integrated with GIT repo as persistence provider, we have to use GIT credentials for remote authentication username/password.

Is there any way to have this done if we set an IAM role with access to that GIT repo (AWS CodeCommit) for the ECS/EC2 that hosting the NIFI application?

We don't want to use any GIT credentials

Could you please advise?
