Backwards Y axis after new board?

Basic Information:

Printer Model: ender 3v2
MCU / Printerboard: mks genL 2.1
Host / SBC linux mint

Hello guys after changing board and setting up klipper i can now control correctly the motors however it seems that my y axis goes backwards when i try to home it. Since my ender3v2 doesn’t have an endstop on both ends, the stepper stalls for a bit then stops homing.
How can i fix this issue?

Just invert the dir_pin ?

From

[stepper_y]
step_pin = PF6
dir_pin = !PF7
enable_pin = !PF2
microsteps = 16
rotation_distance = 40
endstop_pin = ^PJ1
position_endstop = 0
position_max = 200
homing_speed = 50

to:

[stepper_y]
step_pin = PF6
dir_pin = PF7
enable_pin = !PF2
microsteps = 16
rotation_distance = 40
endstop_pin = ^PJ1
position_endstop = 0
position_max = 200
homing_speed = 50

Thanks for the help! That wasn’t exactly the solution but through trial and errors i found that to reverse the movement i just had to remove the ! before PF7.
My Z axis was also reversed and i fixed it the same way

As I described in my post.
