AH-1Z HMD and Head Tracking help

Hi all, I use open track for DCS and have been trying to get it to work with the HMD on the AH-1Z, I’m looking to be able to slew the gun/IRST with my head movement, the way I have thought of is having a button repeater constantly enable sight stabilisation so that it follows my head movement but I’m unsure if it will be against TOS to use 3rd party software.

Any help would be appreciated.
