Is "erase" sufficient to wipe NVRAM to a completely unrecoverable state per the US DoD 5220.22-M standard?

What is specifically defined in this standard is the overwrite all addressable locations with a single character.

The Cisco Secure Desktop (CSD) software ensures the security of client machines that access your network before they are granted access, while they are connected, and after they disconnect.

Before clients are granted access, CSD can verify their operating system, service pack, anti-virus software, personal firewall software, and IP address. Clients are granted or denied access to services and functions based on these verifications.

As client machines work, CSD encrypts information and isolates the connected environment in a Secure Desktop space.

After client machines disconnect, CSD erases and overwrites all data from the secured session to U.S. Department of Defense standards. (CSD uses the Department of Defense clearing and sanitizing standard DOD 5220.22-M.)

I asked about erasing NVRAM on a router, not cached files in a client-server VPN session.
