sda turns to sdb or sdc after install PVE over Debian 12.

Hi everybody

Don't if someone can help out.
I was able to install Debian 12 over a Dell R650xs using 3 NVME.
Strangly enought, the NVMe's appears to me as sda, sdb and sdc.
During the Debian installation, everything goes good.
After install Proxmox over Debian 12 and reboot, sda turns into sdb or sdc.
I have another Dell R650xs that works fine and after install PVE sda remains as sda!

Anybody knows how can I prevent this to happens?

Thanks
