Redmi Note 9 Pro EU (Joyeuse) // Xiaomi.EU V12.5.2.0

Issue:
Can't change preferred cellular network type in settings.

Details:
Whatever I pick from the menu it defaults back to 4G preferred - the menu just closes and if I go back to see what it is it's still 4G preferred. In case I go to the Dialer, issue *#*#INFO#*#* and Phone 1 then trying to set the preferred network it just doesn't work either: some of the drop-down list items work (like LTE only..) but most of them not (like GSM only.. etc..).

My dirty workaround:
I flashed the latest EUXM firmware from here (V12.5.4.0.RJZEUXM). After that it started to work.
