Look into Pi-hole. It's an easy-to-setup DNS server which can run on a Raspberry Pi (or a Linux desktop/server if you have one.) You can then set your devices' DNS servers to the local address where the Pi-hole is running. Since it would be running on your local network, any requests to it shouldn't go through your ISP in the first place. I'd still recommend getting your own router anyways because this kind of ISP fuckery is more common than you'd expect. Plus, your exact configurations follow you anywhere you move. If you do end up getting one, set the local DNS server in the DHCP settings of your router to avoid having to set it on each device.
Doesn't the RPi still go through the ISP? You'd still have to find a way to bypass their hijacking attempts, just on a different device this time.
You'd have to use DNS over HTTPS, DNS over TLS, or DNS over QUIC. As far as I know, PiHole doesn't support these out-of-the-box, so AdGuard Home is a better choice (it's like PiHole but more powerful).
I know PiHole had plans to implement this though, so maybe they do support it now.
You can do it. I set mine up ages ago. https://docs.pi-hole.net/guides/dns/cloudflared/
It's not out-of-the-box though, and requires a bunch of manual setup. On AdGuard Home you just need to enter the DNS URL into the UI and that's it.
