Hey there and welcome to the Samsung UK and EU Community Customer to Customer Forum
As @arianwen27 has indicated, you'll likely have to wait until it is rolled out in the UAE and then most likely you'll have to try to update through SmartSwitch.
Using a device out of its intended region genealogy causes a few issues sadly.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
Since your phone is UAE CSC, you'll have to wait until UAE gets it. However if you want faster updates and you probably live in the UK, I would suggest you manually change the CSC by changing your phone's firmware to EUX or BTU using Odin (Samsung official software, and Frija) which is one of the fastest CSC to get the Updates.
** NOTE **
It's a complicated process but official and will not void warranty or anything. However, if you miss a single step, your phone is useless and will not work and also warranty will ONLY be void if you miss a step or do it wrong.
