EU rom for redmi 9a android 11.. trying to convert from global to EEA

Is it possible to install EU rom on redmi 9a..my current version is miui 12.5.6 global stable but I'd like to switch to EU rom because I dislike some features on global rom.please what is the easiest way to install EU rom... I've tried installing manually with updater app but it tells me "can't verify, other reason"...can I fastboot?
Pls I need solutions...


P.S I'm new here..
