The F-10 branch is created following the procedure to finalize and freeze what is going to be used to compose F-10 GA.
Like with overriding dist tags in koji, create a ticket if you really really need some changes applied to the F-10 branch and give a motivation.
You create a new ticket here:

Remember to supply the commits
Kind regards,
