There probably isn't a binary 5 android 9. If you can unlock the boooader, you can use the modified version of Odin and flash Android 9 regardless of what binary it has.

Yes, the bootloader is unlocked. But what do you mean by "modified version of odin"
Thanks for your reply

There is this:

Patched Odin 3.13.1

For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...

And there is the "Prince Comsy" version.

Now just flash the software, despite the difference of binary

Try it, it can only work and you get what you want or it fails to flash and nothing happens. If it ifails and won't reboot, flash your Android 10 firmware and it should restore your device then you can try again. You may or may not need to/want to try extracting the Android 9 firmware files and the Android 10 firmware files then putting together your own modified Android 9 firmware using different parts of the Android 9 and the Android 10 firmware, mixing and matching the bootloader, kernel and system .img files until you get a combination that works.
