Given Displaylink is a 3rd party driver its probably unwise to upgrade a critical MAC unless the release notes for the driver state that the OS version is supported. There has been instances where it has taken Displaylink close to a year to support new OS releases due to the fact that they need to rely upon Apple for many things. I've still got a M1 running on BigSur but not planning to update that until my new MAC arrives that supports multiple displays natively. Sorry I can not assist more.
