Dimmable constant current LED driver

Hello everyone

I want to drive an LED circuit (already have it, on a fan/light fixture) that was driven with a very strange combination of two drivers (pictures), the second of which had a bluetooth module that also had audio and allowed control with an app.

The thing is, the second module died, and I want to replace it with a NodeMCU as controller, and some dimmable constant current driver (as the original one). The problem is, I don´t know the total load of the circuit (so I drew it) nor if I could use a constant voltage driver and mosfets AND, if I use a dimmable driver, what is the correct way to control it with a Node MCU? (meaning hardware, since I think I´ll be using ESPHome or Tasmota)

What solutions can I use?

Thanks a lot
