What can we do without rooting
I'd probably think about switching to Graphene OS at that point
i used this once https://play.google.com/store/apps/details?id=dnsfilter.android . there are similar apps. they can block a lot, but it will lead to things not working, for example push notifications probably won't work, if you block firebase servers.
Use rethinkDNS, basically it'll use your VPN slot and will set a custom DNS of your choice+filter lists. It has more features tho like wireguard integration.
Without rooting, you can switch to Firefox, install an add blocker, and use a VPN set to an exit node in Europe or California. Alternately, live in Europe or California.
