@Gary2024 I have to admit, I was confused by your post. As someone who has used a third party router for years, I learned long ago to use a different DNS resolver rather than the one the ISP forces customers to use on their locked down routers.
Obviously I don’t have any idea which router you use, but my own TP-Link router, I set it to use Quad9 DNS at router level. I’m sure you can easily do the same using whichever DNS resolver you choose on your own 3rd party router.
