You should try it anyway, I have a rooted lg oled running the latest firmware. Updated a couple of weeks ago.

This will also make https filtering that is used by ad blocking apps impossible since you need to trust a certificate in order for it to work

Some of the apps allow blocking of instances, I use Sync For Lemmy and I blocked pornlemmy and lemmynsfw and I don’t see porn anymore for the most part, there are still some stray nsfw communities on other instances but I rarely see any of their content
