Product: HP Color LaserJet Pro MFP M479fdw

I have multiple M479 printers and the firmware inadvertently got upgraded to CLRWTRXXXN002.2247A.00  (Build date 2022-11-14) and now I am unable to use non-HP toner.  Does anyone know how to obtain an older version of firmware?  Or will doing a factory reset downgrade the firmware.
