I think the command that you are looking for is "erase flash data" .
Please check link below:

This command is used to erase the configuration data in the flash memory of the control board. When the configured data is saved to the flash memory, you can run this command to restore the database to the initial state. After the command is executed successful, the original configuration data in the flash memory is lost.

•Before erasing the data, run the backup command to back up the database file to avoid the loss of important data.

If you want delete or rollback the programs, databases files and extended basic input/output system (BIOS) of the control boards you can try using the command "huawei#rollback"

The system generates an alarm "Rollback complete" after the rollback function is enabled and the system starts to reset.
