In the double slit experiment, if one beamed electrons through the slits at a screen, shining light at the slits and recording which slit the electrons came through, and, before looking at that data, look to see if the result shows two discrete bands or an interference pattern… then…

If the result is an interference pattern, you might infer that "observing" with a mechanism will not collapse the probability waves… and that it takes a conscious knowing (not just a potentially conscious observation) to collapse the waves.

If the results show two discrete bands (showing that the wave probabilities did indeed collapse), and one then erased the data… that would indicate that conscious observation/knowing is not intrinsic to the phenomenon of probability wave collapse… and might suggest that the wave/particles are waves until something specific happens, but discrete particles once something discrete has happened.

Has this been done?
