I have not done it myself, but I found this Guide by SamDark in Github that explains how to create your own template. This is the url: https://github.com/yiisoft/yii2-gii/blob/master/docs/guide/topics-creating-your-own-templates.md
Additionally, if you just want to eliminate the "Create Lab Tipos Movimiento" button you can try modifying the current template which if I am not wrong is located inside the folder vendor/yiisoft/yii2-gii/generators/crud/default/views and the file should be index.php. There you can try deleting or better yet commenting the part of the code that says:
<p>
<?= "<?= " ?>Html::a(<?= $generator->generateString('Create ' . Inflector::camel2words(StringHelper::basename($generator->modelClass))) ?>, ['create'], ['class' => 'btn btn-success']) ?>
</p>
I suggest you to make a copy of the files you modify just in case anything goes wrong.
Hope this helps you.
Have a great day.
EDIT:
Additionally following the answer of schmunk to a very similar question in stack overflow found here: How to use custom templates in gii (using Yii 2)
There is apparently a Gii extension in beta phase to help you in this situation called yii2-giiant found here: https://github.com/schmunk42/yii2-giiant (maybe there are similar extensions that are in a more advanced phase of development, google search should help with that)
