Possible to restrict website access to ten minutes per hour (or similar) - quotas?

I am interested to create a policy that restricts access to number of websites (eg social media, youtube shorts) to a limited period say ten minutes per hour.

A simple schedule (the first ten minutes of the hour) is not suitable, the timer should start when each user hits the policy for the first time (in each hour).

I know that quotas are usually used to restrict time and bandwidth per user, but these reset daily afaik. Or is there a way to create 24 quotas one for each hour?

Open to suggestions on how to achieve.

Many thanks
