Which ones do you want to override?
All user settings are in ~/.config/GIMP/2.10 and most can be set from Edit -> Preferences
Otherwise have a look in the system gimprc file /etc/gimp/2.0/gimprc for the things that can be set (it has explanations) and ~/.config/GIMP/2.10/gimprc for the place to add 'overrides'
