Can I use LT3958 for 80V output as a boost converter, since the power switch (SW pin) is limited to 84V (absolute maximum) ?

Hi ! I want to use LT3958 as boost converter  for 26V input and 80V output. but the power switch (SW pin) is limited to 84V (absolute maximum) , is it safe to operate around 80V at SW pin (power switch). please clarify ! thank you !
