    Lenovo T15 gen 1 secure boot

    Hello,

    I have a Lenovo T15 gen 1 where I can't get the secure boot disabled. I think it is related to the security chip. The BIOS is completely free, no password or anything. The only problem is that the option to disable secure boot is grayed out. Trying to boot it, GRUB 2.02 starts and expects a certain Software. If you want to change something you need to enter a username and password. While experimenting, I was able to load the firmware from the hard drive. There I found signed files, in one also the hashed password (cracking probably not possible in lifetime). It was probably a workstation secured with SINA, which the seller did not tell me... I didn't know that you can protect a system so that you can't even install a new system if the BIOS doesn't have a lock in it.

    Is it possible to disable secure boot anyway? As I said in the BIOS I tried everything...

            some laptops require a supervisor password to be set on bios to change secureboot setting
