Welcome Kurtz,

There’s the (visited:) macro (https://twine2.neocities.org/#macro_visited) that may help you.
Combined with the (unless:) macro (https://twine2.neocities.org/#macro_unless) it looks like (given passage "Room 101 exists):

(unless: (visited: "Room 101"))[[Room 101]]

The link will appear only until the reader visits Room 101.
