I've added these custom startup items and for some reason "kitty --class=startup-kitty-3", "kitty --class=startup-kitty-4", "bash -c "kitty --class=startup-kitty-bpytop bpytop" and "bash -c "kitty --class=startup-kitty-nvtop nvtop" do not start on system boot. Running those lines in the terminal work just fine.
