There are several different implementations of proxies for DNS-over-HTTPS:

https://github.com/aarond10/https_dns_proxy (C) https://github.com/pforemski/dingo (Golang) https://github.com/tssva/dnshttps-proxy (Golang) https://github.com/wrouesnel/dns-over-https-proxy (Golang) https://github.com/CodeFalling/dns-proxy-https (Javascript)

I'd heard that somebody was working on DNS-over-HTTPS support for https://github.com/getdnsapi/getdns at the hackathon in Buenos Aires in April just before DNS-OARC / IETF-95, but have seen no evidence of that.
