If you are comfortable with soldering, you can purchase the latest Hall effect joystick from shopee for cheap.
It's about RM 60 for 10
Shopee link, but you can get it anywhere else.
Take note that earlier hall effect joystick tend to have severe jitter issues. Later versions fixed it.
You will need to disassemble the Dualsense
Unsolder the existing Joystick
Solder the Hall effect Joystick
Hook this up to a computer and calibrate it.
The most troublesome part IMO is to unsolder the existing joystick
Else, there are many who offer this services on Carousell.
Price is around RM40 per joystick.
Given that a dualsense with drift is worth nearly nothing, having those fixed and upgraded into hall effect joystick is really worth it IMO.
Disassemble the controller is a difficult task. I partly damaged my ps4 controller 2 times
The dualsense controller after changing 3 times with Sony still the same. Wasted my time and energy going there
