RaspberryPi 4 display screen

I tried searching the forums, but didn't find what I was looking for, so thought I would ask here.

My Setup
Hardware: Raspberry Pi 4 Model B Rev 1.4
Version: OpenWrt 21.02.3

Question #1: When running on a RasberryPi with a 7 inch touch display connected via the 2-Lane MIPI DSI port, is there a way to put the display to sleep after a given interval?

Example: After booting the display would go dark after 60 seconds.

Question #2: Is there a way to display router information on the screen after boot, WSSID, IP Information, Connected Devices, etc...?

Not looking for anything specific, just exploring the limits with this question.
