Older 4x4 trucks and older RWD platforms, you generally had to take the axle nut off, as the rotor was integral with the bearing race.
That is not the case here - the rotor is separate from the hub. As mentioned, remove caliper and suspended it carefully out of the away - I use a bent coat hanger wire or velcro strap - tie the caliper to the front spring, making sure not to twist/damage the brake flexline. Remove the caliper mounting bracket - has two big bolts from the back side, need lots of PB Blaster or similar - cheater bar helps, if you don't have impact tools. Once that is off, the rotor could should just fall right off - or if is corrosion welded to the hub, use some M8-1.25 machine bolts in the two threaded holes on the hat of the rotor - evenly tighten those and that rotor will press right off the hub.
