What strategies do you use to avoid redundant transformations in Power Query that slow down data refresh?

I'm working on a Power BI project with large datasets that require frequent updates. However, I've noticed that certain transformations in Power Query are slowing down the data refresh process. I want to streamline these transformations to improve refresh efficiency and avoid redundant steps.

Are there specific techniques or best practices to optimize transformations in Power Query and reduce refresh times?
