Ok, but it's not going to work unless you're rooted already. Are you?
First figure out which driver is being used.
I'm partial to using my i2cscan (which will only work if you're rooted).
Code:
# /data/local/tmp/i2cscan
/dev/i2c-2
60 exists
/dev/i2c-4
1f qcom,camera i2c_camera
38 exists focaltech fts_ts FocalTech touch screen controller
/dev/i2c-6
09 wacom Wacom digitizer
38 exists lm3630a lm3630a_bl TI LED controller
/dev/i2c-8
0b exists tc358762 tc358762 Toshiba display interface bridge
68 tps6518x tps6518x TI Eink power management
# cd /sys/bus/i2c/drivers/fts_ts
# echo 4-0038 >unbind
Of course you'll have to do this every time you do a full reboot.
I just did this to my Poke3 and it kills the touch. No problem.
Code:
# cd /sys/bus/i2c/drivers/fts_ts
# echo 4-0038 >bind
