Can we edit BCD file of Windows Mobile 10 ?

Because of OneCore (the fact that all WIndows versions use the same core), the boot process of Windows Mobile 10 seems to work the same way as the desktop version.

In the EFIESP partition, there is a BCD file under ":\EFI\Microsoft\boot". This BCD file can be opened with Visual BCD (Easy BCD doesn't work with this one).

The content of the Xiaomi Mi4 BCD file is below.

Can we edit this this like we do on desktop version? If we can, we may be able to change the boot settings and add a new boot option...

Has someone tried it?
