Doing a little testing with #Privoxy, and #AdGuard's DNS servers https://adguard-dns.io/en/public-dns.html (the latter in lieu of a #PiHole server later).
No way to configure #tvOS to use a proxy (did I miss it?) but custom DNS servers was easy & appears to have had the immediate effect of removing ads on #Peacock and #ParamountPlus. I guess #Hulu is avoiding recognizable ad-servers?
#DHCP + #WPAD is nice: https://www.davidpashley.com/articles/automatic-proxy-configuration-with-wpad/
Irony: Needed this in Privoxy:
