Not as a (good) general solution. Some things are just hard to break down into smaller logical units. E.g. a complicated new driver might introduce thousands of lines of changes. Half a driver usually won't compile, but you could break things down into PRs over individual functions (in call order so there aren't compiler warnings). That's a wildly unnecessary amount of effort though. You could write a skeleton driver first too, but that's rote declarations barely worth reviewing even as part of a larger PR.
