install pve-enterprise (with subscription key) on top of debian install

[DERUMIER, Alexandre]

Hi,

I'm currently working on a hardened pve installation for CIS
certification, and as it need luks encryption + specific partionning,
I need to install it on top of a debian install.

I would like to deploy pve-enterprise repo directly, but how can I do 
it on top of debian ?

The wiki said to install no-subscription first, then switch to
enteprise after uploading the key in the gui
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm

But that mean than more recent packages could be pushed from no-
subscription first.

Is is possible to put the key somewhere in /etc/apt/ ?
