your device most likely uses a different private rsa key that the one used in our guide
you can try to reach out to your device oem (see if they're that generous to provide the key)

the file rsa4096_vbmeta.pem is a private rsa 4096 key
without the right private key used by your device oem, you will not be able to unlock bootloader and for most new spd / unisoc devices the key now varies. it's no longer the same key for all devices

can you check your vbmeta? using the guide @ https://www.hovatek.com/forum/thread-32666.html then post the result here

you can't read the private key from the firmware
either you get from the manufacturer or you happen to luckily find it lying around somewhere on the internet
