Thanks Neil, I have the FlatLaf modules already installed when compiled. I
found that Installer's validate() may not return the correct LAF that will
actually be used. i.e. In validate(), UIManager.getLookAndFeel() may return
Metal and then go on to a later stage where it will actually become Windows (or
whatever).
Anyway, I managed to achieve what I wanted but I'm not sure if I'm just lucky
for now and at some point this won't work due to some async nature of NB
startup, now or in a future version of NB.
Basically, in every module that is likely used early or may do anything
significant in rendering the GUI (TopComponents), I included an Installer
module where I override restored(). It seems that by the time any Installer's
restored() is called, the actual LAF has been chosen by NB (not true in
validate() as mentioned above). So, the first statement in each restored()
calls MyUiSettings.init(). This init() is synchronized and is latched to be
performed only once by first caller.init() checks the current LAF using
UIManager.getLookAndFeel(). If it's not a FlatLaf type, then
UIManager.setLookAndFeel("com.formdev.flatlaf.FlatLightLaf") is called followed
by NbPreferences.root().node("laf").put("laf",
"com.formdev.flatlaf.FlatLightLaf").
As I said, it seems to work although it doesn't feel ideal.

You might also look at configuring the installed look and feels -
https://docs.oracle.com/en/java/javase/11/docs/api/java.desktop/javax/swing/UIManager.html#setInstalledLookAndFeels(javax.swing.UIManager.LookAndFeelInfo%5B%5D)
The NetBeans UI is just showing the installed look and feels. Or you
could hide the existing UI selection and provide your own.
You should be able to validate and change the LAF preference during startup too.
Both should probably happen in a ModuleInstall validate method that
runs after this one -
