I try to avoid filter bubble by doing following things. Not sure of its effectiveness though.
I try to use services w/o sign in when it's possible (reddit, youtube, google). i prefer this kind of services more over services which constantly wants me to sign in.
If some service requires sign in, and seems unavoidable then I try to limit my interactions on those platforms. (linkedin, facebook)
Basically I try to provide least amount my preference or feedback to any platform thinking I would get the generic feed/content. And I prefer using a Browser over apps.
I stopped reading and watching mainstream media. I have also cut my social media use down to just Twitter and Parler for just 30 min per day. Substack is wonderful.
In addition to here I also find that going to conferences or spaces with like-minded people is a great way to find interesting things on the internet. I've found the most interesting online communities from people I know in real life. A lot of people are often more likely to talk about cool things than they are to post about them.
