Update PBA branding without reinstall

Hello!

We using FDE with PBA to secure our notebooks.
Before apply the FDE policy a branding bundle is installed (FDE policy requirede this bundle installed).

Now we must update the brandning to add some information on the screen.
Is there a possibility to update the branding with out decrypting, unassign policy, re-assign policy (installing PBA) and encrypting the device?

I think there are a lot of tools under %windir%\NAC to do this?

Perhaps fdeinit /rebrand

best regards

Andre
