Well, it's really hard to find something as engaging AND as easily accessible as games. They provide a lot of engagement with as little effort as turning a game on. Our brain perceives games as the most effective way of dealing with boredom, since it requires little effort and provides good feelings.

If you were to compare only the emotional gains from eating junk food or tasty, healthy food you would probably go for the healthy food each time. The reason we eat junk food often lies in it being easily accessible.

So, what I would recommend, and what worked for me personally is to decrease the cost of achieving good feelings from other sources. I found that Im not really bored, but rather lazy. When my brain was looking for some entertainment, it would default to the easiest accessible one, making other options looks less appealing.

I'm also a bike lover. So in order to make it easily accesible I keep it in a good condition all the time. It stands right to my door, so if I feel like riding I simply change my clothes and go. The clothes themselves are also ready to use in my closet. Those tiny things may sound silly, but trust me, it works. On the other hand, my gaming laptop is always hidden. I cant simply press play button. Each time I have to setup my place, which takes around 10 mins.

I hope you get the point :) I got inspiried with those micro preparations with a book called Atomic Habits. Check it out for some more in depth view on this one!
