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.
My device is an S25 Ultra.
