downgrade android version from 12 to 10

[5g_tester]

Hi all,

Is there a way to downgrade the android version from 12 to 10. I was tried to unlock the oem which is not happening from fastboot and there is no option in developer options. Does anyone know a way to downgrade the version.

Thanks in advance.
