Can someone make a scripts or lml to stop local towns sheriff spawn?

[Gary Connor 2]

I'm using RDRFR, and I know most towns they have their own sheriffs such as Malloy, Thomas, Farley, Freeman etc. I can use RAGE or Trainer to set my player model as these people anyway, but I cannot stop these NPC spawn in the town, that cause I can see twin guys in the same place..... I tried to kill them by force but they'll respawn in any time. Just want to know if there's anything that can stop them spawn or respawn after killed? And hope it just like a switch, I can easily turn this on or off, and custom set these in one or more places and not just a button press and every towns lose their sheriffs
