Have a look at this thread:No, I updated using the official updater in the settings of the device itself. I'm on EEA version MIUI V13.0.12.0.SJSEUXM

[Firmware] Xiaomi Mi 10T Lite / Mi 10i / Redmi Note 9 Pro 5G (gauguin) [Auto updated!]
Xiaomi custom users face a problem with firmware updates. As there are many devices with no one to provide the newest firmware update every single release, and developers who provide updates to devices may forget or be busy sometimes, so releases...

It is always recommended to flash the latest firmware. That is independient from the ROM (except that the Firmware and ROM must be for the same Android version).
