You are able to force devices to use a specified DNS. even when they have hard coded DNS in them. Your router/firewall must be able to support redirection of network traffic though.
Yes but I think only very few applications use a hard coded DNS server. And under all those applications who use a hard coded DNS server is probably a very low percentage that uses encrypted DNS.
You need to use an IP address (as opposed to FQDN) for DNS because when your computer starts up, it won't be able to resolve the FQDN to do DNS lookups.
My computer uses unencrypted DNS and sends the queries to my router. My router does the encryption for forwarded DNS queries sent to the internet. There's no need to encrypt DNS traffic in a LAN unless you don't trust this LAN. The WAN (internet) is where evil people try to snoop on you.

This probably won't work if the hard coded DNS is DNS over HTTPS

Or just a hardcoded IP, lol
A hard coded IP would mean it's unencrypted DNS which can be force-redirected to your router with NAT rules.
True, don't know how I missed that.

Cloudflare DNS over TLS famously is using the IP address of 1.1.1.1: https://developers.cloudflare.com/1.1.1.1/encryption/dns-over-tls/
