Veon ultra smart 4k tv's

Heyo guys,

Just wondering, how do i block the stupid ads on yt on my tv?  I got the tv last week.  I cannot seem to change my DNS on the tv, but I have got it on my router.  

All the adblocking studd works on my phone (except for when using the app) and PC.  I cannot seem to find a decent browswer for my TV either that I could download to put watch YT like that.  

Any suggestions?
