Frame challenge. What you want is 1 switch to activate all the lightslight (yet, and that'sthe motion sensor only controls some). That's making people chase expensive obscura, and proposing marginally-Code solutions. What is easy is 2 switches to activate all the lights.
Blow out the motion sensor box to a 2-gang box. One gang gets the motion sensor. The next gang over gets a plain switch.
It's already true that the motion sensor gets always-hot. Extend/pigtail that so the plain switch also gets it.
Ditto ditto ditto, switched-hot.
Now, the switch at the motion sensor will override the motion sensor.
Note that if the motion sensor does not have a neutral, this will make the motion sensor lose power. That may wipe out its memory of normal day/night light levels in this location. So you might see some "motion sensor turning on lights in daylight" behavior for a day or two after overriding it. If you don't like that, get a motion sensor with a neutral.
