Can I limit per-device bandwidth consumed per day during peak hours

[charris]

My ISP has data caps that apply to bandwidth consumed during peak hours (7am-11pm).

Occasionally a device (or user) will go a bit crazy and download 100GB+ in a single day, which cuts severely into my cap.

I want to limit all devices to 5GB/day each during peak hours and let them download whatever they want during off-peak hours.

I've been searching the forums, the docs and even asked ChatGPT, but so far I haven't found a solution.
Is this possible?
