In Drupal, getting node author details programmatically which are configured with view mode is simply possible with the node preprocess function, here is the code.

theme_name.theme

<?php

/*
Initially, you have to write the preprocess code in the .theme file to get the required 
fields data like author uid, target_id, and other required values. */

function theme_name_preprocess_node(&$variables) {
/*first we have to check, for which type of content the author belongs to */
if(($bundle_author == contnet_type) && $author_view_mode == 'full'){
/* if author has the content then get the node of the author in this variable */
    $node = $variables['node'];
/* getting author uid */
    $node_author = $node->get('uid')->getValue();
/* getting author target_id */
    $node_author_uid = $node_author[0]['target_id'];
/* finally loading the author in the final variable */
    $author = User::load($node_author_uid);
/* getting the entity type */
    $entity_type = 'user';
    $entity_id = $node_author_uid;
/* assigning the view mode machine name */
    $view_mode = 'view_mode_name';
    $entity = \Drupal::entityTypeManager()->getStorage($entity_type)->load($entity_id);
    $view_builder = \Drupal::entityTypeManager()->getViewBuilder($entity_type);
    $pre_render = $view_builder->view($entity, $view_mode);
    $variables['author'] = $pre_render;
}
}
/*after this preprocess function you can able to print the author variable with all the enabled view mode fields.*/

node-page.html.twig

<?php
{# If you want to render all the fields programmatically then write a separate twig file or else simply you can print the variable in the required template. Now I’m going to print the variable in node-page.html.twig, as shown below. #}
<div>{{ author }}</div>
