Hotspot - can activated vouchers be switched off at a fixed time?

Hello specialists,
is there a way, maybe a script, to turn off activated vouchers every day at 11:45pm.

I mean the users (=Vouchers) under IP/Hotspot/Users and NOT under IP/Hotspot/Active or IP/Hotspot/Hosts.

I would like the voucher to be turned off at 11:45pm and not after…minutes or hours. So at a fixed time.

Many thanks and best regards
