MKS Gen L v1.0 + TMC2209 V3 UART problem

Hi all i have problem and i dont know if it is software related or hardware... I hope you can help me out.
Recently i bought MKS Gen L v1.0 board with 5 TMC2209 drivers for a cheap. Problem is i cant get them work vith UART.
The drivers are a little strange, on all TMC2209 that i found on tutorials there are 3 pins, but on mine only 2.
Drivers are fysetc 2209 v3. Here is a link [wiki.fysetc.com]
As a hobbyist that schematics wont really help me coz i dont understand it...
I tried all i could, solder 1k resistor on one pin, tried with two separate wires one on tx one on rx pin, tried to swap plases, tried to remap dedicated pins, #define SOFTWARE_DRIVER_ENABLE on and off, ... no luck
Here is my configuration and some pictures. Pls help i really ned printer to work thanks in advance

Mixing brands of electrics components is a bad idea. They use different pinout standards.

In this case
you need to remove all jumpers under the stepper module.
you need to cut the lower pins on CK and RX, make sure they are not connected to the motherboard.


Firmware:
leave SOFTWARE_DRIVER_ENABLE disabled.

Example for X axis

the pins file defaults to
#define X_SERIAL_TX_PIN 40
#define X_SERIAL_RX_PIN 63

If you want 1 wire mode on tmc2209 on two wire controller
you join TX and RX on top of tmc2209 then wire it like you have with a 1K resistor on the controller TX line

you can also just use 1 wire on tmc2209 and 1 wire on the controller.
you join TX and RX on top of tmc2209 and wire the one wire to the RX pin (has to go to RX pin, it has change interrupt capability)
and updated pins to.
#define X_SERIAL_TX_PIN 63
#define X_SERIAL_RX_PIN 63

Hi thanks for the answer i will try that, just one more question vhat is ck pin that i need to cut on TMC2209 v3 ?

I didn't solve problem ... Pls help
