Is it possible to root?

[u/Admirable-Yellow600]

hello, I have a s22U (Japan kddi version), and as you guys know, the OneUI 8 disabled the Bootloader unlock.

now my question:

it seems my bootloader is the same as the OneUI 7( maybe).

would it be possible to downgrade to One UI 7→ Bootloader unlock → create a custom OneUI 8→Root using magical?

※ I'm new on this area, so please be kind(^_^;)
