No, Protect macros generally never change hotbars because they're just used at the start of an instance to cast Protect without using up one of your Role Action slots.

Example:
/micon "Protect"
/mlock
/merror off
/aaction "Largesse" off
/aaction "Protect" on
/ac "Protect" <wait.3>
/aaction "Protect" off
/aaction "Largesse" on
