DTLS 1.3 does not really change this aspect compared to earlier DTLS versions.

We could reference a number of the other TLS WG documents that attempt to reduce the size of the certificate message, such as

Client Certificate URL
Cached Info
Certificate Compression
Following the guidelines in RFC 7925
Other certificate types

It may be possible to use the fragmentation mechanism to send one certificate after the other in the certificate chain.

Is this what you had in mind?
