You can use some of those crowdsourced lists of hosts files to ban trackers, ad networks, and the like, i.e. https://github.com/StevenBlack/hosts https://github.com/StevenBlack/hosts or https://github.com/notracking/hosts-blocklists https://github.com/notracking/hosts-blocklists, you can use pi-hole even as a docker container https://github.com/pi-hole/docker-pi-hole https://github.com/pi-hole/docker-pi-hole or install it in your router.

You can combine multiple VPNs an/or Tor, with VMs. Mirimir wrote some articles on that setup. If you want to go full in you can use QubesOS, although now Joanna Rutkowska left the team. I'm sure there are other options...
