next time I do one of them I will leave some mines at the boss location, on entering the cell the next time the mines should go off killing him if everything works as planned.

Yes it will only work once so you have to reach him the next time however you can then leave new mines. so you only have to clear the location half the time

brilliant! hope that works. Dunwich Borers gets old!

Won't work. The area just resets, undoing ANYTHING you've done in the past.

Look for "No Settlement Attacks"or"Disable Minutemen Radiant Quest"mod.I been using the first one since launch without any problems.

This. I tried it one time, the mines just went away when the enemies respawned again.

Ok, i thought dropped stuff stayed. however mines might be reset with the mines enemies put out.

A shame as it would be fun.

Yes I know you can mod it out but its no problem avoiding Preston if you want eiter.
