Module development and code questions

Hello.

I would like to know if there is any possibility to execute more than once ajax commands in hook_form_alter?

Controlled by if constructs?

I have a form that has to be quite dynamic, that has to act on the fields, visible/invisible through form #states or another possibility.

In short, there are 5 fields that have to be visible/invisible through the variables that receive the if constructions.

What is the most appropriate way for this process?

I am using drupal9 via nginx reverse proxy. Using the below nginx configuration.

This happens only when image is loaded (uploaded) for the first time.

Image gets the .webp format and it's Content-Length becomes smaller but the browser still tries to get the bigger Content-Length - from the original image format.

Steps I do:
