Is it possible to alter the domain on a field via a server action?

Let's say I create a server action to run when the product_id is updated for an sale.order.line. Is it possible to run python code in that server action that will adjust the domain on the route_id field in the view?

I can see in the documentation that programmatically this is possible:

But how would I accomplish the same thing via the Odoo UI Server Action tool?
