Get a Minivan, drive it fast on rural roads...catnip to deer.
Problem solved
There is really no one answer other than layered defense...the suggestions above are excellent.
I do not know what the laws are where you are, or the lay out of your property, but I allow hunters to set up stands and hunt my farm. You can even specify bow or shotgun only. I vet everyone.
There is a crazy amount of deer here.
