"Intel Connectivity Performance Suite"/"Intel Killer Performance Suite" silently leaks DNSΒ #2120

What happened:
"Intel Connectivity Performance Suite" is an app that comes preinstalled with my laptop ASUS Zenbook 14 UX3405MA, and there is seemingly no way to uninstall it.

It seems to be a rebrand of "Intel Killer Performance Suite", a network boosting thing originally from Rivet Networks.

With it running, I am leaking DNS even when portmaster shows the connections in the UI:

I have set quad9 as my DNS in portmaster, and cloudflare is configured on my router
I also have "Ignore System/Network Servers" turned on

Disabling the driver using this guide:
https://support.lenovo.com/us/en/solutions/ht513263-how-to-completely-uninstall-intel-connectivity-performance-suite-driver-from-a-system
solves DNS resolution and portmaster returns to working as expected.
But a windows update ~2 days later re-installed the driver as Intel Corporation - SoftwareComponent - 40.25.725.165, making the issue present again.

What did you expect to happen?:

As ICPS is doing strange things to the network stack, I do not expect portmaster to be able to stop it. (If it is possible, that would be nice, as it seems to be a somewhat common app for newer high-end intel laptops) But it should be able to detect it as a DNS leak and warn the user, as currently there is no feedback of something being off.

How did you reproduce it?:

Both of these should install the driver, but it seems to have some sort of OEM restrictions about what chipsets they can be installed on.

Debug Information:

It was too long for the issue, but I believe most of it is applicable
