Easiest way is with a 1-10V POT, one POT can dim upto 30 drivers

Thanks for the reply,

I have some 50K OHM potentiometers at home. It works to dim 2 drivers but I am not sure if it will work with 3?

Also, I noticed a couple of ppl are using remote control dimmers. I'm looking for one of these with a remote control that has pre-set buttons to dim at 25%, 50% and 75%. Do you know where I could buy one of those?

Take a look on eBay, you may find something. They make some with IR remotes in China that are cheap

Nope, you'd need a 100k/3= 33k pot

RapidLED makes a simple 0-10V dimmer that will do several drivers at once, grab one here: https://www.rapidled.com/cased-potentiometer-with-knob/

I already checked the remote dimmers on eBay, Aliexpress and Amazon. But I am not sure which one would be the best for my usage. Most of these dimmers seem to be made for very low-power LED strips

Would this one work if I strip the wires?

That looks like a pwm dimmer, you need to search for 1-10V dimmer or 0-10V dimmer

So something like this? https://www.amazon.ca/-/fr/dp/B07V44NCP ... ay&sr=8-62

That's the one

I could be missing something but I have one of those dimmers from rapid and it only allows my hlg -240-2100 to go from 10%~50%
