If users need to make a choice you can differentiate from primary buttons with a secondary buttons. Or style it as a link if the choice is less important.
Having multiple primary buttons creates choice and a lack of clear direction for the user.
Primary buttons are great for guiding users through each step of a workflow
Making the button visible will help set expectations and with a clear call-to-action will give the user context.
Presenting the primary button only after a set of actions reduces visibility for users. They won't know when they can expect the action or what they are trying to do in that step.
While it is a sure way to stop users from carrying on, it creates a jarring experience.
Users will also lose the ability to click the button to learn if what they entered is right or if they made a mistake.
If you do disable buttons you must provide another way for the user to continue, add an error message or text to explain why the button is disabled.
