This is not quite correct. There are ways to gain information about a quantum state without interacting with it: https://en.m.wikipedia.org/wiki/Interaction-free_measurement

Do (non)measurements taken this way 'collapse the wave function' anyway? Or can you only get information that is still open to change during the actual measurement?

"Collapse" is just one way to explain how measurements happen. These are "actual" measurements, because they give you actual information.
