You cannot do that. The DS record algorithm field is expected to
match the exact algorithm used by the dnskey it is referring to,
by protocol definition.
One option is to wait until the registry supports the particular
algorithm codes for the DS record, or you can always sign again
the zones, but this time with one of the supported algorithms
(but you cannot double-sign and mix NSEC with NSEC3).
