I am not sure I understand your problem exactly.
I have changed the LED, but not the driver. The actual LED emitter is soldered to the round MCPCB (metal core printed circuit board). Are you trying to swap entire emitter boards and driver boards? Swap a new emitter already on a board? Swap just an emitter? Having trouble just opening the head?
Changing just the LED requires a reflow soldering technique. The round LED board should come out of the head after unsoldering the 2 wires, there should be a dab of thermal compound under it.

have you tried putting a needle nose plier into those two holes and turning it?
ya . already. it is not turning.. and the edges of those holes do got damaged a bit. tried the same on two lights . no luck

Pull out the driver since you have a new driver. Tear it up then pull out everything else. It's probably press fit in there then epoxied.
Easiest thing is to order a host from fasttech or aliexpress and build one.

If it's like other old Fenix/47s I've come across it's both. The driver and led reside in a sort of threaded can that is thread locked into the head. This is what makes the Fenix lights able to withstand drops and other abuse.
As you've already discovered the board is too fragile to turn, you'll only destroy it if you do; which is an option if you already have a replacement.
In some models those solder points you can see are soldered to pins that actually connect to the LED PCB. If so, they would need to be desolder before the board will lift off. It's possible that desoldering from the emitter side will be adequate. In any case the object is to lift the driver board out of the way so you can unscrew the can.
Once the driver is out you will be able to better unscrew the aluminum can itself out of the head with some pin pliers. A little heat to loosen the thread lock first might be needed but not too much because the optic is plastic.
