How can I access the product attribute fields in the Magento 2 admin panel from a custom module using CSS and JS?

Question

Magento

In the product edit form (Catalog->Products->Product) I have 3 custom attributes: select and two datetime.
It is necessary for me at a choice in "No", to hide two others.
I'm trying to connect CSS and JS in a module (app/code/Namespace/Module/view/adminhtml/web/js/my_js.js) and attach an event to the select, but it doesn't work, apparently because the form is loaded by Javascript much later than the DOM .
Tell me, how can I "influence" form fields through JS and CSS in my module?
