On Ubuntu and Kubuntu 20.04.2 LTS you can find out if your system has been booted securely by running the following command:

sudo mokutil --sb-state

The result will be something like:

SecureBoot disabled or SecureBoot enabled. Here an example where the system has not been booted with secure boot.
