Question Can We Unlock WiFi 6E(6GHz) by flashing to EU firmware?

Can we Unlock the Support to WiFi 6E(6GHz) support on the Snapdragon 888 by flashing the firmware to EU version?
Like the default China MIUI firmware won't support 6Ghz when it's not enabled in China, but I don't know if there's 6GHz RF and Antenna which could allow us to flash the phone to EU version, then able to connect my new router which supports WiFi 6E(6GHz).

I couldn't unlock by EU fw. To unlock 6GHz, We have to use Custom ROM that MIUI based such as Xiaomi.eu and MMX, and set Wi-Fi region(on additional settings) to UK or South Korea.

May I know if your hardware is bought from China, or it's the CA/US/EU/HK version?
I wasn't sure if the China version is having 6GHz antenna or not...

As far as I knew, it's the Xiaomi12/pro which is using Snap 8Gen1 which has the 6G support for sure.
Then I can flash the MMX or Xiaomi.eu to Xiaomi12 to get it support 6GHz.

There's no clarification from Xiaomi.eu official support 6Ghz wifi so far...
I just searched on their forum, there's basically nothing there

My device (Mi 11) is global version. and I have 6GHz router. I hope use 6GHz on AOSP roms such as Pixel experience and Evolution X but it can't cuz can't change wifi region on it. Pixel 7 and 7 Pro support 6GHz for sure after Dec 2022 update. I want Xiaomi 12 but Xiaomi 13 will support Wi-Fi 7 soon.
