How Do You Disable Forced Collision on NPCs?

How do you DISABLE forced COLLISION on an ANCHORED NPC WITHOUT using COLLISION GROUPS? I tried to disable the collisions in a constant loop, but it does not work. Do you know any way to stop the forced collision? OR How do you make the Camera go through certain added parts like if the parts had no collision.

local Children = script.Parent:GetChildren()

for i = 1, #Children do
	if Children[i]:IsA("BasePart") then
		coroutine.wrap(function()
			while true do
				Children[i].CanCollide = false -- Disables collision for every part in NPC
				wait()
			end
		end)()
	end
end

THANKS!
