Will changing the CSC to a supported region unlock the bootloader? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

I'm in the United States with the bootloader locked. If I used SamKeyl to flash, say, a South Korean CSC and flashed a South Korean firmware, would that allow bootloader to be unlocked?
And would the bootloader remain unlocked if I flashed a United States firmware afterwards?

CSC has nothing to bootloader unlock.

G950f original CSC TEL wnat to change to BTU ot XEU

I have tried various how too's without much success. I can change the CSC to a non OXM CSC but when ever I try to flash a multi OXM CSC it always comes back to TEL.
I've tried with my UK 02 sim in to no avail although I am trying to do this whilst in Thailand if that would make a difference.
When I flash a OXM combi file in AP it will flash on its own but not with a CSC file, Have I got the wrong Combi file? when i try *#243203855# nothing happens.
Also when I flash a supposedly multi csc firmware XEU, PHE, when I go into the bootloader it says single sku.
In download mode it tells me the OEM lock is Off does this mean the bootloader is unlocked? As i dont have the option in dev options.
Any help would be appreciated.

Thanks. How did you change the CSC? (simply flashed the different CSC through Odin?) Did you have to unlock the bootloader first?

Changing firmware of different region

Is it possible to change stock firmware of SM-A505G with SM-A505U1? I unlocked bootloader in download mode, but when I try to flash SM-A505U1 firmware to my SM-A505G handset it says Fail to install firmware. Is there any way to change firmware of different region?

Korean Bloatware/branding

So I got a refurbed phone that apparently originated in Korea (n976n)
I tried flashing the OEM KOO CSC firmware as opposed to the branded firmware (i.e. sktelecom) but after successful Odin flash, the sk telecom splash showed, and the bloatware and custom UI remain.... What is going on here?
Is there any way to get unlocked, no carrier influenced SM-N976N firmware?
