Thank you for reporting this bug. Your report shows that you had an unattended upgrade that ran and upgraded the version of the nvidia dkms module that you have installed; and that this triggered a request from shim to disable SecureBoot on your system, because dkms modules are incompatible with SecureBoot currently.

Do you remember being prompted previously about turning off SecureBoot? Did you elect not to turn off SecureBoot? Or, did you choose the option to disable SecureBoot, but not confirm this selection on reboot?

This may be the same as bug #1694986.
