Date Filter / Week Starts On

Hello,

I use filters that this plugin seems to ignore. The most important is changing the week to start on Sunday.

gform.addFilter( 'gform_datepicker_options_pre_init', function( optionsObj, formId, fieldId ) {
    optionsObj.firstDay = 0;
    return optionsObj;
});

A secondary is no dates prior to today, less important.

gform.addFilter( 'gform_datepicker_options_pre_init', function( optionsObj, formId, fieldId ) {
    if ( fieldId == 5 ) {
        optionsObj.minDate = 0;
    }
    return optionsObj;

How can I achieve this with Gravitizer?
