Ask HN: How to self-censor our news

Given the COVID-19 situation, my fiance and I will be working from home for the forseable (minus a few days here and there). We are informed of current affairs and recognise that we must play our part despite not being at risk physically. However, our mental health will likely be suffering - mainly thanks to the constant news updates and habits of checking it that we've formed, and the fact that we won't have an office full of people and meetings scheduled to keep us focussed on actual work.

What's the cleanest way to block a list of websites of our choosing from our home wifi? I don't want to tunnel all our traffic through a VPS or anything as there will be a lot, and I understand that it won't help when I'm using work's VPN. Perhaps setting up a DNS server on an instance and getting DHCP to tell the clients to use it? We're using MacBooks and iPhones mainly.
