I've put together a build script that I use already for my Ubuntu setup... Working for 5.9.16, and just installing 5.10.4 to test that too... But the results from above already speak for themselves... (Thank you bro
)
Hopefully this can simplify the process...
It downloads the current DisplayLink, then updates the EVDI folder from the above instructions...

[AS PER BELOW - I've updated my script to allow for newer DisplayLink updated to not be automatically be patched]
##IMPORTANT##
You may also need to run this to start the service after reboot:
sudo systemctl start displaylink-driver.service
Let me know if it helps
