GIT: how to merge two branches without actually merging files (trivial merging)

Question

Is there a way in git to merge two branches without merging the file? In other words, just draw a merge arrow.

Say I have branches A and B. I need to merge branch B into A, but you do not need all the changes in B, but most likely you need to bind the branches together.

git checkout A
git merge B --no need changes

In general, there is a way to merge two branches without submodules. I want to save the submodules, as in branch A, and still need to merge branch B.

Update

git merge -s our BRANCH_NAME worked for me.

Answer 1

git merge -s ours B , , B . , B A, A A.

Answer 2

git reset ORIG_HEAD --hard .

, git merge, git commit --allow-empty --allow-empty-message --no-edit . git merge gitk git log --oneline --graph, .
