Hey! I also use the Creality K1 Max and have tried a few rolls of Creality Hyper PLA. For Cura, here's what works well for me:
Nozzle temp: 210–220 °C
Bed temp: 50–60 °C
Print speed: You can push up to 300 mm/s (Hyper PLA is designed for speed), but I usually get better quality around 200–250 mm/s
Retraction: 1 mm at 40 mm/s
Cooling: 100% after the first few layers
