boot – Linux does not detect internal storage when booting from an external drive

I'm using a Dell D11S machine, booting from the internal SSD is working. If I boot from an external storage (UEFI boot, Debian LVM on LUKS, SSD connected with a USB-SATA adapter), the internal SSD is not detected by Linux.

Release of lsblk:

NAME SHIFT: MIN RM SIZE RO TYPE MOUNTPOINT
n / a 8: 0 0 223.6G 0 disk
Dasda1 8: 1 0 142M 0 part / boot / efi
Dasda2 8: 2 0 620M 0 part / start
Sda3 8: 3 0 222.9G ​​0 part

Debian - vg-root 253: 1 0 222.8G 0 lvm /
SR0 11: 0 1 1024M 0 ROM     

I have checked the BIOS settings, but I have not found anything that could indicate that it is a security feature.
