As the question states, I am simply trying to disable my touchpad on my HP laptop. So I think this is very specific for the HP Elitebook 840 G5 as I have tried the following generic methods to disable the trackpad:
- Under mouse settings, using the Synaptics tab. This tab does not exist for me. (Reference https://support.hp.com/us-en/document/c03882926)
- Disabling the Synaptics driver. I thought this would work for sure too but I tried to disable all of the mouse drivers available under Mice and other pointing devices (Device Manager) and the trackpad still works.
- Using third party software. I tried "touchpad-blocker" and even when enabled, the touchpad still works.
- Double tapping the top left corner (https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/how-do-i-disable-a-touchpad-on-an-hp-elitebook-850-laptop/td-p/5480918) This does nothing for mine.
I am open for other suggestions. I am really surprised that disabling the driver didn't work.

PC Settings --> Touchpad --> Leave touchpad on when a mouse is connected. Uncheck the setting the disable the touchpad when a mouse is connected.
