this is weird, did not know some of them came out without the offroad functionality.
Subscribed for what you manage with ktm!
In you case there wont be a cut in power, so its only less throttle response (line in rain mode) with offroad traction control which allows rear to spin twice as fast as front wheel (iow not good enough for sand, but very good for normal gravel riding)
offroad ABS will disable abs on rear but keep it on the front wheel, do you have that?
if you really want some kind of offroad mode, best my 1190 ever was was with broken speed sensor, so cut the wire and put a switch in. You will have permanent MTC off but ride in street mode throttle response, full power.
