No. It was a lie, because the US did not have enough N95s, and they were worried that if the public bought them, there wouldn't be enough for healthcare workers.
The "we didn't know it was airborne at first!" is such a laughable lie that only US/EU folk believe it.
There is no new evidence or new way to determine if Covid was airborne that was discovered recently. The evidence and ability to confirm this, was always available.
