Turn off CSS selection feature on calendar

Hi,
I'm setting up the Appointment+ calendar the page listed below.
Is there a way to turn off the theme's built in selection feature on this page (where it's highlighting any section of the calendar I hover over with a gold colour).

I think it's this:
/* Selections */
*::-moz-selection {
background-color: #dba124;
}
*::selection {
background-color: #dba124;
}
