You can set the date picker type to "datetime" and implement something as below with a default time value 00:01:
<coral-datepicker type="datetime" name="field" value="2021-05-27T00:01+05:30" valueformat="YYYY-MM-DD[T]HH:mmZ"....">
</coral-datepicker>
FYI- Any subsequent coral updates may break this implementation so direct change should be avoided unless urgent.
