How to edit ventoy_grub.cfg

[balanga]

Is there any way to amend ventoy_grub.cfg from within the grub menu, or do I need boot some OS first?

Such a feature would be useful.

Any grub entry can be edited IIRC.  Just press 'e' on the menu entry you'd like to alter.  Or am I missing something here?

 
If I get to the grub> prompt I can run

grub> ls (hd0,gpt1)/ventoy/ventoy_grub.cfg

and this shows

ventoy_grub.cfg

but I don't see any way to edit it. Is there a way?
