Hello jeronimo89
Sorry, we do not provide customization support. But it is possible with Custom CSS. I can give you hints.
If you want to totally vanish a menu item, then use this CSS to Template Options -> Custom Code -> Custom CSS
@media (min-width: 768px){
.sp-menu-item:nth-child(2) {
display: none;
}
}
It will make your Agenda menu item disappeared for Desktop view.
Similarly, if you want to show the menu item but disable the link, then use this CSS to Template Options -> Custom Code -> Custom CSS
@media (min-width: 768px){
.sp-menu-item:nth-child(2) {
pointer-events: none;
}
}
It will show your Agenda menu item but the link will be disabled for Desktop view.
Best regards
