How to change the size of a diff in a merge request in Gitlab?

Question

GitLab

Hello!
I want to reduce the output of the diff in the merge request, but all the methods I found did not lead to success.
Found in this:
app/models/commit.rb: DIFF_SAFE_FILES = 100
app/models/commit.rb: DIFF_SAFE_LINES = 5000
app/models/commit.rb: DIFF_HARD_LIMIT_FILES = 500
app/models/commit.rb: DIFF_HARD_LIMIT_LINES = 10000
but too did not help.
Has anyone come across?
