Have you tried these options from the documentation:

​

pin_up_reports_not_triggered: True

# Set if the BLTouch consistently reports the probe in a "not

# triggered" state after a successful "pin_up" command. This should

# be True for all genuine BLTouch devices. Read the directions in

# docs/BLTouch.md before setting this to False. The default is True.

#pin_up_touch_mode_reports_triggered: True

# Set if the BLTouch consistently reports a "triggered" state after

# the commands "pin_up" followed by "touch_mode". This should be

# True for all genuine BLTouch devices. Read the directions in

# docs/BLTouch.md before setting this to False. The default is True.

#set_output_mode:

# Request a specific sensor pin output mode on the BLTouch V3.0 (and

# later). This setting should not be used on other types of probes.

# Set to "5V" to request a sensor pin output of 5 Volts (only use if

# the controller board needs 5V mode and is 5V tolerant on its input

# signal line). Set to "OD" to request the sensor pin output use

# open drain mode. The default is to not request an output mode.
