Are certain changes not supposed to go into master?

Question

git

There is an old project in git, I
selected my own branch
, made some changes in it (defined build events, broke some references to projects, let's call them commit_1)
how can I now merge master to myself and merge other changes from my branch into master while that -would commit_1 not go to the master?
------------------------------------
Reformulation of the question
There are changes in the branch that go nowhere (to other branches) should not go
How can this be done?

Answer 1

Your question is not very clear.
But it looks like you need git cherry-pick
