I'm not personally releasing a ton of internal packages where I work but I know of https://github.com/tox-dev/tox-uv. Haven't tried it yet though but it seems to do what you want. I also saw that nox (tox but in python instead of a tox.ini file https://nox.thea.codes/en/stable/config.html), is supporting uv from what I understand.
tox-uv has been a great selling point for my personal use of uv. I'm typically testing across 4-5 different versions of Python and the build speedup has been significant.
