How to restore the system from a backup if the system disk is encrypted?

Question

Encryption

Actually the question is in the title. Let's say I encrypted the entire hard drive, including the system one. At some point, something happened to the system and I need to restore a backup from an image ala Acronis | Aomei, etc. How to restore the system without removing the encryption from the partition? There is an idea to use VeraCrypt for disk encryption, for example. In WinPE, mount an encrypted partition through VeraCrypt and restore not the entire image through the backup program, since the entire old partition is removed and replaced with a new one, but only the files from the image. I don't know what will come of it. Any ideas how to implement something like this?
Eventually:
1. You need to restore the backup NOT removing the encryption from the "C" section. Therefore, it is impossible to restore the entire image of Acronis and others like it, since when restoring an image, the old partition is deleted and a new one is restored. The encryption is removed.
2. There is another option. In WinPE, mount the encrypted partition "C" and restore ONLY files from the Acronis image without restoring the image itself. In this case, you must first delete the old (all) files from the "C" drive, and with them the encryption program that was on the "C" drive and which is responsible for the bootloader, when you turn on the computer, you must enter the password from the encrypted partition. It turns out not an option to restore both the backup image and separately the files from the image.
