is secure-boot enabled? If so, have you read and followed the steps required for secure-boot process, which are listed at the link you provided?

Yes I did check that as well

mokutil --sb-state
This system doesn't support Secure Boot

Why do you think that the dock requires the displaylink drivers?

According to Dell, dock WD22TB4 is a Thunderbolt 4 dock. Thunderbolt docks don’t need those drivers. Have you connected the dock to the thunderbolt port of your system and authorized access to the system?
