imx8x manually revoke key

Hello,

 

Is it possible to revoke a key "manually" on the imx8x soc:s?

 

This was possible on the imx6 -parts by issuing a special unlock command in the CSF to allow writes to that fuse bank. For the imx8x the documentation seems to indicate that the _only_ way to revoke key's are by setting the revoke parameter in the csf in combination with the "commit" command.

 

Is it possible to access the revocation fuses without changing the csf?
