You should find the needed files in the pac file for your model

Is there no problem if you apply it as it is?

see @ How to create a custom signed vbmeta.img for Unisoc using AVBtool (hovatek.com)
root @ How to use Magisk Manager & boot.img to root Android (hovatek.com)

thank you.
There is one thing I would like to confirm.
Even if I refer to .pac which can be downloaded from the official, there is no boot.img and only boot.img.flag is found. Where should I find it?

Extract the PAC file, and rename boot.img.flag to boot.img

So that's it…
I'll try.
Thank you

If the .flag file is 0kb then use a lower version of Research Download tool to extract the pac
