Wyse 7020 ZX0Q secure boot

I have above thin client.

Someone gave this to me to replace a raspberry PI.

The problem that I run into is that I can't use it for what I want to because I can't turn of Secure boot.

This option is not in the BIOS.

Someone know a workaround or a different options like replacing the BIOS with a version were I can turn of Secure boot.

Hope someone can help me
