Essential features like git bisect or git blame are not as useful if commits of a merge/pull request are squashed. Please disable that functionality.

https://docs.github.com/en/github/administering-a-repository/about-merge-methods-on-github has the details. I’d vote for Merge pull request. (For the other options, https://docs.github.com/en/github/administering-a-repository/configuring-commit-squashing-for-pull-requests shows where to find it in the settings.)
