sensorless homing tuning hits other end

How should I tune sensorless homing? Now if I set

SET_TMC_FIELD STEPPER=stepper_x FIELD=SGTHRS VALUE=255

SET_TMC_FIELD STEPPER=stepper_x FIELD=SGTHRS VALUE=255

and

G28 X0

G28 X0

, it will detect stall immeditely and then try to move the the mid point of X carriage, which it now thinks is 150/200/250 mm towards the other end of the rail, and might hit the y extrusions. My question is really that how do I stop the override of G28 that moves the head to the middle. Tried looking at "homing_override", but only found reference to that in config/Ratos/klippy/ratos_homing.py, which seems to get registered in ratos-common.sh. However, this started to get a bit convoluted, and might be I am missing something, so I thought to ask.
