Can I remove cart functionality

Hi

I’m trying to remove all cart functionality from my website. I’m selling online courses and when a student buys a course I don’t want to have a cart system, I just want the to take the student directly to the checkout.

I have figured out how to skip the cart page, but the problem is that the course is still added to the cart, so if the student go back to the shop and clicks on another course, the checkout also shows the previous course.

Is there any way to just completely remove all the cart functionality all together?

Thank you.
