Are there third-party alternatives to the Cisco SSD for Catalyst 9300s yet?

So, according to Cisco's document about installing SSDs into the Catalyst 9300:

"You must use only Cisco USB drives; non-Cisco USB drives are not supported."

Has anyone figured out how to, you know, ignore that, and use a disk that isn't the SSD-120G from Cisco, list price 1500 damn dollars? Like "service unsupported-transceiver" but for SSDs?
