You don't need to specifically disable 6to4, if those devices are 
well-behaved and prefer IPv4 to 6to4, and you're not connecting to
IPv6-only services from IPv4-only-plus-6to4 clients, and you're not
putting 2002:: addresses as destinations into DNS.

"Fixing 6to4 with anycast relays run by volunteering networks that 
do not guarantee anything" is not possible.  

Emphasis on the "anycast relays" bit.
