How to program data limitation to be applied after a specific amount of time for hotspot user?

All is said in the title.
I want to set a data limitation for hotspot user but this must be enabled after a specific time.
That is a limitation which should be taken into account by the router only after a specific amount of time has elapsed.
Is it possible?
