Maybe it helps to know, that the base font size of the UI can be changed with command line parameter "fontsize". Have a look here:

matthias@enterprise:~/src/netbeans/nbbuild/netbeans$ ./bin/netbeans --help 2>&1 | grep fontsize
  --fontsize <size>     set the base font size of the user interface, in points
matthias@enterprise:~/src/netbeans/nbbuild/netbeans$

The font size of the treeview should be derived from that.

Open etc/netbeans.conf, add --fontsize 16 to the netbeans_default_options.

Thank you everyone, I finally found a better adjustment method that will not interfere with other UI styles.

Use "FlatLaf" custom mode and add a piece of setting code
Tree.font=16
That's it
