    Here you can find it. I don't think there's any other way to downgrade, especially from 10 to 9.

    Of course there is.
    Use a computer.
    Erase your device.
    Flash a complete ROM.
    Do it at your own risk, though.

    You can go back to Pie and then get Android10 over OTA... You got the link for Pie because you asked for it.
