Welcome to HP Forums @DBFR,
Thanks for the post.
I understand that you are looking to disable the touchpad on your notebook.
Not to worry, I will be glad to help.
Have you tried any troubleshooting steps on your own?
Most of the notebooks have a hidden button towards the top left corner of the touchpad, please double tap it a small light will light up on the touchpad.
When the light is On the touchpad is disabled. Please refer to this HP Article for assistance and for the other features of the touchpad.
Let me know if this helped.
