Protect master branch for been visible to developers

Problem to solve

We can't make master branch invisible to users in the project

Intended users

It should be applied on developers permission

Proposal

Suggesting to add a new option for master protected branched to be invisible ( files ) to users with developers permission. In this case, only admin can see the master branch and the other can see the other branches

Permissions and Security

Can be only for developers permission ( developer should not see the master branch )

What does success look like, and how can we measure that?

I guess a lot of people might need it. Especially when a new member of a team is accessing the git and the owner don't want this member to see or access the master branch, instead he/she will access the other branches that might not contain everything in the master branch
