Commenting out rather than deleting -- intentional? If this is temporary, consider adding a date annotation so it doesn't rot forever. Also, the H100 variant is still active, so L4 coverage is being lost. Is that acceptable? If the H100 test covers the same ground, the commented-out block should just be deleted.

I am not the person who setup this test. So I would not want to remove the test completely, do you know who would be the best person to ask if we want to remove this completely?
