dd command missing?

[Steve2926]

The dd command seems to be missing from grub2.
I want to copy sector x to sector y on same disk, can this be done in Ventoy grub2?
Also hexdump command does not support getting values into a variable (see a1ive's grub2 hexdump command for example).

These are extended commands in agFM grub2, so not included in Ventoy's grub2, also not used by Ventoy.
