Basically, yes.

You can use OMAPI but I wouldn't recommend it, it is not as easy a
tool to use as one might like.  If you're in a testing environment,
you can also use the silly 'infinite-is-reserved' config command that
auto-reserves the lease for the client if they specify an infinite
lease time; if you can coax the client into requesting an infinite
lease time, that is.
