Yes. This is exactly what I would prefer to do. My current plan is to round up all the PR requests, at the start of each new sprint (every two weeks), and make it the first development task in the sprint.

The problem though, is that so far, I can't point to any literature online, to support this idea.

I would still like to keep Dependabot, because the diagnostic step it performs is useful. But introducing new dependency upgrades daily, even minor upgrades, seems like a recipe for trouble. Minor upgrades are just as likely to introduce a vulnerability, as they are to patch them, after all.
