Yes. You can make it so that a customer doesn't have to select price options and fields.
Also, you can show the resource's calendar immediately after the widget is loaded.
Open the resource settings and set the the checkbox Skip reservation step.
For correct work the resource must have only one price option.

To open the resource's calendar immediately, open the widget settings, go to the Content panel and switch the View mode to Calendar.
