Is it possible to block youtube in a particular device only (TV) ? cant find what I am looking for in parental control/dns filter
You can try in Ai-protection/parental control add your TV mac-adress and test to block the media option Internet radio and TV and streaming and see if that works
I guess you could write some firewall rules and block IP's that belongs to Youtube?
I did a fast google search, and found this site that lists the most common IP's related to Youtube:
https://www.lifewire.com/ip-address-of-youtube-818157
Now add all them to the GUI firewall "Network Services filter" with the source IP from you TV, and destination IP from the list above.
Not the easiest way, maybe a bit ugly, but it will work.
