We need to way point like point A to B ,
At point B it need to land and disarm, for physical switch like push button, press it at poin B than after within 10 second takeoff and go to next waypoint or RTL which we can set.
Is it possible like this to add physical switch which can work for next waypoint or RTL
Yes, see continue after land and buttons on wiki.
Can you please share a link, we need it to do by physical switch on drone not by rc switch.
You just need to search, or explore the documentation - it’s all there

And if you look at the blog entries for The Outback Challenge - the rules stipulate that the LED must be green for safe (disarmed) and red for unsafe (armed), opposite to what we normally have. There’s a setting for that too.
