How to disable nvngx_update.exe during automated test

Hi, I’m programmer from Ubisoft, we use automated test to test our game. Recently we encounter an issue that when game is launched, multiple “nvngx_update.exe” processes are spawned, and those processes remain even after the automated test finish and game is closed, which result in false alarm for the test.

Since it is automated test, we want to remove any process that might result in requiring human interaction, and software updates on our test machines are already controlled by our IT department, so we don’t need any auto-update.

I tried to following the instruction here: NVIDIA Update|NVIDIA.
but that article is outdated as there is not “Updates” option in the Nvidia Control Panel Help menu.

I have also tried uninstalling GeForce Experience but the problem is still there.

Please advice how to disable nvngx_update.exe, thanks.
