We can set minimum quantity as by default for woo commerce product using following code

We have used the Plugin Min Max Quantity plugin from WP Repository and that plugin saves the Min Quantity in post meta min_quantity

add_filter( 'woocommerce_quantity_input_args', 'comcast_woocommerce_quantity_changes', 10, 2 );
   
function comcast_woocommerce_quantity_changes( $args, $product ) {

	
	$id = $product->get_id();
   
   if ( ! is_cart() ) {
  
      $args['input_value'] = get_post_meta($id,'min_quantity',true); // Start from this value (default = 1) 
  
   }
   return $args;
   
}
