Restrict automatic synchronization on mobile phones

Hello, Im beginner in mikrotik.
There is a network problem in our company.
Upload speed is not too much and should use in a limited way.
Restricting people is not the solution. this time we can’t use upload at the right time.
How do I restrict automatic synchronization on ios and android phones?
The problem of unwarranted and untimely synchronization ruins the whole line. Can I turn off sync with port restriction?
I think I can solve this way. I would appreciate if you help.
Thank you all.

The easiest thing you can do is setup simple queues on your router in order to limit the upload of those devices…
