I did not find how to boot unsigned kernels on Xiaomi RedmiBook 14 :(

[Kai-Heng Feng (kaihengfeng)]

Secure Boot has to be dibbled in the BIOS.

[Kai-Heng Feng (kaihengfeng)]

s/dibbled/disabled/

[ALEKSEI VOLKOV (softkot)]

There is no such options in the bios.

Recent 5.6.4 kernel with latest firmware git pull does not get it alive.

[Launchpad Janitor (janitor)]

[Expired for linux-firmware (Ubuntu) because there has been no activity for 60 days.]

[王滋涵 (wi24rd)]

I tried kernel 5.8 and latest firmware or try change QCA6174 with kvalo's firmware [1] and re-modprobe in a live CD, however, it's still broken like above.
