SF11 and ADR for plain LoRa

Hi, I’m checking the AIR time calculator https://avbentem.github.io/airtime-calculator/ttn/eu868
which is for TTN networks, and I’m wondering if the constrains for SF11 and SF12, namely they can be used only when ADR is enabled are also applicable for plain LoRa communication without any networks and protocols like LoRaWAN?
