You need trenches, or something similar, if you are going to mount any kind of lasting defense. Specifically, you need a safe way to run your logistics (or in military terms: your lines of communication, which refers to your supply lines, not your phone lines).
A lone bunker is incredibly difficult to resuply, relieve, or reinforce. That is the power of trenches. They give protection for when you need to move goods, people, or information. If you can cut a defensive position off from any of these, it won't stand up very long.
You can still use such positions to delay. But Ukraine needs to hold territory, not delay it's loss.
