I wanted Tree supports and all the extras that came with Cura 5.4 but was apprehensive about moving away from the 4.8 Elegoo provided for fear of messing things up. My new Neptune 4 is rock solid now and printing amazing prints so I finally took the plug and did it. I couldn't be happier. So here is what I did. Very easy.
1. I made screen prints of all my settings. You can copy your existing Start Code and End Code if you want or use the Elegoo defaults below. If you have made changes to your start or end code make sure to copy and paste it to a notepad for step 5.
2. Uninstalled Cura 4.8 and deleted all the files in both Program Files\Cura and Program files (X86)\Cura and C:\Users\%youruserprofile%\AppData\Local\Cura
a. You will want to save any profile settings you have in cura now by exporting them or screen shots because you will have clean install with no Profiles, Plugins etc.
3. Rebooted computer
4. Installed new cura 5.4
5. Set up Elegoo 4 Printer
a. Select Add Custom Printer
b. Name printer Elegoo Neptune 4
Paste the below Start Code:

Extruder 1
Save and that was it.
I closed reopened downloaded all the plug ins I wanted and I was in business. Take some time to adjust the settings.
I also needed to create a PLA setting custom so my default printer temp and build plate temps would be correct as the Material settings dictate the temps.
Otherwise I LOVE IT. You will need to add the Option "Support Structure" in settings to be able to select the dropdown Tree Supports.
Happy Printing.
