Instructions are:
1. Uninstall displaylink driver.
2. Enter macOS Recovery mode
3. In terminal enter command:
csrutil disable
4. Boot to normal macOS and enter command in terminal:
sudo touch /Library/Extensions
and reboot
5. Boot to normal macOS. At this stage kextstat | grep DisplayLink should be empty
6. Enter command in terminal
sudo csrutil clear
This will enable system integrity protection disabled in step 2.

So I went through all the steps above, and kextstat | grep DisplayLink was indeed empty after that. However, when I went back into recovery mode after completing all the above steps to input the kextcache -I /Volumes/MyDisk command, I got a similar output as before as seen in the attached screenshot. And for whatever reason it was no longer recognizing the kextstat | grep DisplayLink command now too..
