Welcome to the forum
A suspension lift is going to be your only option, seeing as the R50 pathfinder does not have a traditional frame, making a body lift impossible. It’s a unibody, so it’s all together and nothing can be lifted off of anything
You’re also maxed out at 2” when it comes to lift in the front because anything more will be breaking your CV axles (unless you do a subframe drop, but that’s a whole different beast). Also, most people agree that it’s best to use longer springs as the basis for the lift rather than spacers that sit on top of the coils because the longer springs do not cause the CVs to bind since the suspension travel is still limited by the strut length, meaning that the truck will sit higher naturally but the wheels will never flex/drop lower than the stock amount, so the CVs are never beyond their operational angles. They will however still mess up the CV boots over time because they sit at a more extreme angle than they otherwise would, so it’s recommended that you also install manual hubs so that they aren’t constantly spinning while you drive. This will make it so that the boot wear only occurs when your 4WD is engaged.
Anyway, you best bet for the front if you are looking at doing the full 2” of lift is to go with the AC 2” front lift coils, and pair them with any 2”-3” lift coils in the rear, whether they are the matching AC ones or Land Rover defender coils. You can also go with Old Man Emu front coils in either the Heavy Duty our Medium Duty flavors, but as far as I know they both give slightly less lift than the AC coils, with the HDs being the higher riding of the two because of the higher spring rate.
These are the front AC lift coils and the OME coils are easy to find with a search

The forum has a TON of info to go through regarding both the front and rear options, I would recommend doing some searching so that you aren’t waiting for responses, as the forum can be a bit quiet sometimes
