I know what you’re facing. I have similar issues with my children. I’ve skimmed and read through most of the responses you’ve received here. My input on this issue is that my children were issued Chromebooks that are managed by an mdm and which send everything through a VPN which prevents any kind of monitoring, blocking, or filtering at home or any other network they connect through. The only solutions available to me is to constant over the shoulder surveillance or MAC blocking, but there are several neighbors who have a strong enough wifi signal that my son can and will switch to one of them (the ones he knows the password to or using the open guest access). Physically locking up the laptops when homework is done and at night is what I have ended up doing.
