Is it possible to somehow upload a file to Symfony without "moronicity"?

Question

symfony

Colleagues, good evening.
I'm trying to upload a file in Symfony 4.
There are tons of examples on how to do this.
Do I need to say that I don't get it?
I don't want to use forms, I don't have forms in my project.
All examples/solutions assume the use of a form.
I just want to upload a file to a specific folder, perhaps write information to a database.
No, you need to hang a lot of prePersist, preUpdate ...
Create some forms, and also mess with the service.
Take an example here
