Non interference is when belt broke, the valves are either fully or almost closed. Turning th camshaft with the piston at TDC would become an interference engine. When turning the camshafts some valves need to fully open so it will touch the piston top.
Turn pistons away from TDC then turn camshaft to desired position. After that only turn to TDC.
