Can you switch through official ROMs with the bootloader locked?

Hey there, does anybody know if switching through official forms of MIUI is possible with the bootloader unlocked? Like, is it possible to switch to the EEA or TR version with the Global rom being concurrently installed on the system? If not, what is preventing one from doing so?

No.
You need to unlock the bootloader.
In order to unlock the bootloader you have to sign on the phone with a valid Miui account, only with that account you will be able to unlock the bootloader.
For more details about the unlock process read the official page: https://en.miui.com/unlock/download_en.html

Hmm... Though, I'm sure you can flash between official Xiaomi ROMs (accept Chinese) and just relock your bootloader without issue, how does that differ?

Indeed, once flashed an official firmware you can locked the bootloader without any issue, without an account. Just run a command like:

fastboot oem lock

(obviously in Fastboot mode)
Only the unlock process require to have a valid Miui account registered on the phone prior unlocking. Because the unlock process require a token from Miui server.
I'm referring to steps used by a regular customer. I don't know what can be done on a service.

So, if i am not mistaken, i should theoretically be able to get a global device, unlock the bootloader, flash eea, India or any official ROM & lock my bootloader without problem yet i can't do it without unlocking first, right?

Yes, you are right.
