I'd look at your forks first, are they air? You can try with less psi to see if that helps. And look at rebound (too fast?)
Then look at bar, stem and saddle setup.
If you can have a look at your body position on the bike, it might be you are pitched a bit too much forwards so putting more weight on your wrists than need be.
Angling saddle, shorter stem, rotating bars can all help reduce the weight on your wrist, which should help you ride lighter.
(I broke both wrists so spent quite a while getting setup right on my bikes to reduce pressure & vibrations)
Expensive solutions could be things like carbon bars help with trail buzz.
