Detailed walkthrough
Kill 3/3 Farmhand Supervisors.

The Supervisors are Protectron robots and are not limited to being located at the farm. There is one on the south end of town in Flatwoods by the Red Rocket gas station, one is usually near that same area but, more to the East of the Church on the less commonly used road in Flatwoods near a downed telephone pole, and for the third supervisor - head to the West of the Agricultural Research Center. A Farmhand supervisor is on a road near a barn with tractors in front of it.

Use the Agricultural Center's mainframe terminal' to 'Change the Mr. Farmhands Targeting Parameters'.

The mainframe terminal where you can 'Change the Farmhands Targeting Parameters' is the Basement of the agricultural building. It is to the right as you walk into the basement of the agricultural building next to an orange light source. The staircase to the basement is toward back of the building to the north. Like many events in Fallout 76 - this is an area search. You cannot rely too heavily on the Diamond quest markers to guide you, since they just lead you to the doors to go back outside to Appalachia and then back inside into the Agricultural Research Center. You just have to search the Area for the stated quest item.
