If you installed your system in UEFI mode, you must disable secureboot for modules installed by dkms after installation.

You can check installation mode with following command.

[ -d /sys/firmware/efi ] && echo "EFI" || echo "BIOS"

You can check status of secureboot with following command.

mokutil --sb-state
