After updating my bios version to f 29, I can no longer downgrade, it says corrupt bios file, I think there is a measure against downgrading in the f 29 version, I wrote to support but I could not find a solution, I need to downgrade, how can I do it, I can get advice

Yes, you are correct.
After installing BIOS vF.29 you are prevented from going back to an earlier version as indicated in the release notes:
https://ftp.hp.com/pub/softpaq/sp158001-158500/sp158197.html
- Due to the security updates installed by this BIOS update, previous BIOS versions cannot be reinstalled after this BIOS update is run.
If there is a problem, you will have to hope that HP addresses any issues with a future BIOS update.
