Does it exist a way to make part touchable only for the local player character

Hi, I’m currently working on an obby, in which there are several hundred killbrick.

Many of them are in motion (prismatic, cylindrical and other), so they touch each other and fire the touched event function a lot of time. So many times that these events cause a lot of lag for the game on mobile devices or old PCs.

Is there a way to make a part touchable only by the player character and nothing else? Thank you !

---for i,clone in workspace:GetDescendants() do
if clone:FindFirstChild('KillBrick') then
			clone.Touched:Connect(function(hit)
				if hit.Parent.Name == plr.Name then
					if rs.gameEffects.Invincibilityg.Value == false then
						hit.Parent.Humanoid.Health -= 10
					else
						for i,v in workspace.Tour:GetDescendants() do
							if v:FindFirstChild('KillBrick') then
								v.CanTouch = false
							end
						end
					end
				end
			end)
		end
