If you have any geospatial data, you can tile it with tippecanoe [0], which gives you an mbtiles file. Protomaps lets you easily convert the mbtiles file into a protomaps file which you can then use.
Protomaps doesn’t limit you to any particular type of tiles, it’s just a format which allows you to read tiles out of a single file with HTTP range requests.
Most blockers are running through Safari Extensions, so they’re limited to whatever Apple allows them to do. It’s no uBlock, but I made an app that lets you run your whole device’s traffic through a blocker [0].
