Can we have total discrimination between switch iSW as a main upstream in a panel with downstream iC60N/iC60H breakers ?

There is no discrimination concept between isolating switch and circuit breaker as the discrimination exists between two protective devices , but the switch ISW is a switching ON/OFF device on load and doesn't have tripping curves or protective c/cs  , if we want to check the discrimination we have to check with the upstream of the isolator switch ISW and the downstream breakers

The attached PDF is about discrimination concept .
