In my opinion your best bet is to replace that sheet of magnets with 3M flexible magnetic self-adhesive sheet.

I've used that with all sorts of Z probes and they seem to work just fine.

I used to be a fan of BuildTak until the went with a sheet of little magnets - I've moved on from them.

The bed can be adjusted with screws and Z has a stepper. Leveling via a 4 point macro, which doesn't work when I check it with paper. The 2 screws in the front are ok, only at the back both screws are too far away from the nozzle. If I manually level the heightmap comes from above.
