I run a tech upgrade service dedicated to Playstation 5 Controllers. I Repair/Upgrade drifting Duosense and Edge controller joysticks to modern technology parts that never develop stick drift issues. I can install pro caliber hardware upgrades to Dualsense Controllers to give them 2 or 4 back buttons and (optionally) slider controls to set your R1 and R2 Triggers to switch between normal pull triggers or as clicky buttons (for more immediate results when using an in-game weapon). I also perform custom shell design upgrades transforming basic white or black controllers into whatever colours and metallic coatings on a part by part basis to make your controller unique to your design. Finally, I have a small inventory of completely upgraded controllers for sale with upgraded Joysticks and optional upgrades available. I have the required equipment and training to perform this work, which means you get peace of mind that your controller won't end up damaged like it could if done DIY or by a friend with a soldering iron. If you feel up to DIY then I encourage you to give it a try but research the techniques and tools required first - It will help you decide which way to go.
