Completed Merge Request where we need to move one change to prod without the other

I had a set of changes to separate pages "create-edit-req-line" and "Registration - Start" which were created in a sigle merge request. I'm now going to need to have the change in the "create-edit-req-line" page go to production much sooner than the change to the "Registration - Start" page. I have not Merged to Main but into a different branch. How do I move the one change to prod without the other. Should I create a new merge request and redo the change I need to go to production. Thank you
