Using CSS you can hide those details. You can set a custom CSS class for the field if you want to be specific or you can just include the following CSS in your custom CSS file.
In your custom CSS file you can include the following to hide the details:
/* To cover all fields */
.objectDetails>li {
display: none;
}
/* To specify a single field, note the space after the custom class */
.customFieldClass .objectDetails>li {
display: none;
}
