   * If you don't have secureboot keys and `sbctl` is installed, generate them with `sbctl` before generating the UKI files. `booster-um` will by default sign the UKI files with `sbctl` tool if it is installed. If you don't like that, set the `sign_uki: false` to the config. 
   * If you want to use the manually generated keys, use the `sbsign` tools instead of the `sbctl`. Install the `sbsigntools` and set the `sbsign: true` to the config. The `sign_uki` must not be disabled and you will need to provide the appropriate key paths within the `sbsign_config` node (usually `secureboot_private_key` and `secureboot_certificate` fields	need to be configured)
