Modify NOR to switch from SSD default partitions

[simkard]

Dear All,

Has anyone being able to modify the SSD partitions the PS5 boots on by changing some values in NOR ?
Accordingly to this article, there are system backup partitions : PS5 Developer Wiki - Partitions
I know there are dozens of settings/values in NOR, but is there any for switching/forcing boot on backup SSD partitions ?

Thanks !
