Win11, issue with getting DNS from DHCP

In a windows11 based laptop, it always taking 9.9.9.9 - regardless what DNS my router is broadcasting, ignoring the DHCP.

Router has a static IP assigned to the mac address of this device. Same goes for all my devices - all gets fixed IP details from address reservation.
Rest of the devices are getting the proper DNS provided by router DHCP, except this windows system, and that too only in wifi mode - its always taking 9.9.9.9 DNS - as if its hardcoded somewhere, but it's pretending as if its getting auto DNS from router
When connected via wired LAN its is taking the correct DNS served by router.

Tried all possible troubleshooting - even resting the LAN adapter nothing helped.
Even tried tethering phones, connecting to other routers - Nothing works. its always taking that quad9 DNS regardless what is being broadcasted by the wifi source.

Anyone has any idea what going on and how to fix it ? 9999 means its bypassing my pihole which i dont want. right now.
