Block Snapchat Spotlight?

Hi,

My young son has snapchat on his phone to keep in touch with his friends, but yesterday he asked me how to turn off Spotlight as it's very distracting. Spotlight is a tiktok/reels-like infinite video feed that was added to Snapchat.

There isn't anyway to turn this feature off in the app so I wonder if it's possible to block the spotlight address/domain at my virgin router instead. I've done a bit of digging and found the following:

• It's not possible using the VM router, so I need to use a pihole or use the VM router as only a modem and buy a new router?
• It's not possible in Child/Web safe either, as they don't recognise the URLs suggested in this reddit thread: https://www.reddit.com/r/pihole/comments/sl3xa8/block_snapchat_discover_stories/

Does anyone have any suggestions?

Thanks.
