It is possible to use an additional ULA at home to address computers. This ULA can be taken to a new provider because it is only valid inside your network - not on the internet. Then the GUA prefix is being used to connect to other computers on the internet outside your network. Your computer can have multiple IPv6 addresses, it already has at least 2 (link-local and GUA).
