Will dumping the partition to enable `oem unlock` and flashing back the edited partition work for unlocking the bootloader on Huawei devices?

I'm trying to unlock the bootloader/FRP of several Huawei devices. But it is difficult because there is no support from the manufacturer and the oem unlock is not present in the system. So, I have come with the next method: Since the main partition is formatted with erofs - Compile the kernel module (for Linux) to enable support of the partition. - Next, dump the whole partition into an image file. - Change the format into one editable. - Mount an edit the /system/build.prop, to enable oem unlock option. - Flash back the edited partition. - Try to unlock the FRP/bootloader. Does this method have viability? Or I'm missing something? Alternatively, the whole partitions system can be dumped and flashed again, but I can convert the erofs > ext4. This last one, AFAIK, should pose no problem, but since I'm not too used to android (EMUI8/9/10) well.
