How to set DNS on Phone

I have a Raspberry Pi on my network, configured as Pi Hole. And the router's DNS points to this. This removes most ads from devices connected to the network.. On one particular app (10Play) in Australia, it complains about an adblocker. Interestingly, every other TV app works fine. The only issue I can think of is the Pi. Is there a way on Samsung S24 and Samsung S20 to set the DNS for a particular Wi-Fi connection? I have looked at Settings under the Wi-Fi connection. The only thing visible is DHCP/Static option. I haven't changed this as I don't really want to use a static IP address. - Ideally, I would be able to set the DNS on say 2G, but leave 5G profile alone. - I am not looking to do a deep dive via rooting or ADB
