Here you go, Adrian.

.am-event-list .am-event:hover {
background-color: white !important;
}
.am-event-list .am-event {
box-shadow: none !important;
}
.am-event-list .am-event .am-event-data {
cursor: auto !important;
}

If you wish to add a border around it, you can edit the second row, like this:

.am-event-list .am-event {
box-shadow: none !important;
border: 1px solid lightgray;
}
