There's going to be a thread for the discussion of the week in the TTY before it starts.
Mainly it's going to be the same as the two previous years, you can refer to the thread in the op. In sum: just no X/Wayland. That means the framebuffer is allowed.

For a lot of people it's not feasible at work.
There's one solution to that: you bring your home laptop and use it as a terminal that ssh into your work machine and when you really need graphical stuffs you can use your work machine. However, this all depends on if your company allows you to do that.
