Possible to use custom dhparam for tls?

Hi,

can I use an individual dhparm file with elasticserach tls? If possible I want to be able to use a cusrtom dhparam for rest api and for transport.

Do I need to append dhparam fragment to the cert (if using pem mode), is there a parameter to load the dhparam file explicitly or will kibana just ignore custom dhparams?
Is it posisble to use custom dhparam with .p12 files?

Thanks, Andreas
