If they are using DHCP-PD, then, it comes with a lifetime whether it is
static or not.

The reality is that unless they need to renumber you, you'll probably get
a new RA with the 60/90 minute lifetimes specified each time RAs are
sent and your counters will all get reset to 60/90 for the foreseeable
future.  The preferred and valid lifetimes aren't limitations, they're
minimums.  The prefix should be yours and should be functional for
you for AT LEAST the valid lifetime.
